The Complete Aviation Personnel Safety Guide

In the aviation industry, safety is often discussed in terms of flight safety and pilot training, but aviation safety starts on the ground with ground crews, maintenance teams, and engine and avionics technicians. These teams that inspect, maintain, and prepare aircraft operate daily in environments filled with hot surfaces, elevated work areas, and intense time pressure, making ground operations a high-risk zone for accidents, injuries, and operational disruptions. Additionally, these teams play a vital role in protecting the in-air safety of pilots and passengers by ensuring that critical avionics instruments and engines are operational.

For commercial, military, and executive aviation operations, personnel safety is a critical layer of risk mitigation.

This guide outlines the most significant risks aviation personnel face, explains why traditional safety approaches fall short, and explores how ground support equipment can dramatically improve safety outcomes. It also provides actionable strategies to implement a comprehensive approach for your operations.

The Biggest Risks to Aviation Personnel

Instrument-Inflicted Injuries

Avionics sensors, probes, and wicks can be sharp, fragile, or hot. Ground and maintenance personnel may encounter:

• Cuts and lacerations from protruding static wicks, antennae, or other instruments
• Burns from recently operated systems, heated probes, or accidental system activation
• Impact injuries from bumping into hard-to-see components

These risks are often overlooked until personnel are injured.

Falls from Ladders & Wings

Inspecting surfaces and engines or installing and removing protective covers may require technicians to climb ladders or maintenance stands, walk on aircraft wing surfaces, or strain to reach higher avionics instruments.

This creates a high risk of slips, trips, and falls. Even a fall from a relatively low height, such as the wing of a small aircraft, can result in serious injury, particularly when tools or equipment are involved.

Strain and Muscle Fatigue

Aircraft avionics covers and engine barriers - especially older or poorly designed ones can be heavy and difficult to maneuver, awkward to align and secure, or installed in positions that require overreaching or twisting.

This risks repetitive strain injuries and muscle fatigue. These injuries are cumulative and often underreported but significantly impact workforce health and productivity.

Environmental and Operational Stressors

Aviation ground personnel operate in challenging conditions:

• Low visibility during night operations
• Extreme temperatures on the tarmac
• High winds that complicate installation tasks
• Time pressure during quick turnarounds
• Noisy and chaotic environments

These factors increase the likelihood of mistakes, improper installations, and accidents.

In-Air Incidents or Accidents

In addition to their own safety, ground crew personnel can also impact the safety of pilots and passengers in the air. Mistakes made on the ground can cause in-air accidents. A single incident can put ground crews, pilots, and passengers at risk.

For instance, during pre-flight operations, a pitot probe heat cycle could be triggered accidentally, causing a pitot probe cover made from cheap vinyl or polyester to melt onto the pitot probe. Now, not only is the probe a burn hazard to ground personnel, but the melted cover has damaged the pitot probe, which will cause faulty readings in the air. Depending on the pilot’s ability, these faulty readings could be solved by safely returning tothe airport or could result in an injurious accidents This one incident was caused by two simple mistakes: 1) maintenance leaders chose cheap gear, and 2) ground personnel failed to remove pitot probe covers before flight. It resulted in damage to the aircraft, injury to personnel, potential injuries to pilots and passengers, and slowed operations by causing unexpected turnarounds or aircraft incidents.

Traditional safety measures are not enough to prevent small incidents like these, which can have catastrophic cascading impacts on safety and efficiency.

Why Traditional Safety Measures Fall Short

PPE is Reactive, Not Preventive

The primary traditional safety measure for aviation ground crew is personal protective equipment (PPE). PPE, including helmets, gloves, and safety harnesses, plays an important role, but PPE alone doesn’t eliminate risk.

PPE mitigates injury after exposure to risk. It does not eliminate the hazard itself. For example, gloves may reduce cuts, but they do not remove sharp edges; harnesses and helmets help after a fall begins, but do not prevent it.

Well-designed covers can prevent these hazards. High-temperature avionics covers stand up to heat and prevent burns. Static wick covers eliminate sharp points, preventing cuts. And pole-installable solutions prevent falls by eliminating the need to climb ladders or stand on aircraft surfaces.

Equipment Design is Overlooked

Traditional safety approaches rarely consider how protective ground support equipment itself may contribute to risks. Poorly designed or outdated aircraft covers and engine barriers can require dangerous positioning to install, fail to protect personnel from cuts and burns, and lack visibility.

The answer is not to buy more PPE but to invest in cover and shields that do not put personnel at risk. Gear that protects aircraft without risking personnel safety.

Human Factors Limit Effectiveness

Human factors can limit the effectiveness of safety procedures and PPE and increase the risk of errors and accidents. The combination of fatigue, stress, and time pressure can reduce implementation of proper procedures and increase the likelihood of injury. Highnoise environments combined with hearing loss can reduce situational awareness, increasing risk of injury.

Not only does poorly designed equipment increase likelihood of injury, but it is also less likely to be implemented by crews. Covers that are slow, dangerous, or taxing to install and remove are often left in storage, unused.

Additionally, even well-designed equipment can pose a risk to ground or flight safety if improperly installed and removed. Equipment procurement is only half the battle. Crews must also implement protocols, strategies, and training to ensure safety and proper equipment use.

Operational Safety Protocols & Systems

Equipment Selection

The first step to increasing personnel safety is choosing equipment that does not require them to risk their safety to protect aircraft, but that simultaneously protects personnel and the aircraft. Key features to consider when procuring protective equipment for engines, avionics, and other aircraft instruments that also support personnel safety include visibility, ease of use, and durability. Additionally, choosing equipment that works together as a unified safety system can increase safety and streamline operations.

Equipment Care & Inspections

Proper care and regular inspections ensure covers and shields remain intact and free of damage or wear that could compromise their effectiveness. Neglecting care and maintenance can lead to costly repairs, operational delays, and safety risks. For example, a damaged pitot probe cover could fail to protect the instrument, leading to faulty readings.

Pre-Flight Risk Mitigation Strategies

Pre-flight operations are hectic and fast-moving. Equipping teams with risk-mitigating strategies helps them do their jobs and navigate these bustling spaces safely and efficiently. Pre-flight risk mitigation strategies can include proper installation, removal, care, and storage of aircraft covers; assigning these key responsibilities; and inspecting instruments and engines for damage, foreign object debris, ice, or snow buildup.

Personnel Training

Proper personnel training ensures ground crews understand the correct procedures for installing and removing covers, reducing the risk of foreign-object damage or equipment left in place during takeoff. Training programs should emphasize standardization, communication, and accountability. Hands-on instruction helps personnel learn proper installation and removal techniques and recognize improper fit, worn materials, or signs ofdamage that could compromise safety. Training can cover the operation of specific equipment, knowledge of aircraft-specific risk areas, and the rehearsal of risk mitigation procedures and strategies.

Proper ground personnel safety is vital to their safety and the safety of pilots and passengers.

ROI of Aviation Safety Systems

Investing in aviation safety is not just about regulatory compliance. It is a strategic decision with measurable returns directly impacting efficiency and reliability. Investing in ground safety can reduce injury costs, minimize aircraft damage, improve operational efficiency, raise operational reputation and credibility, and increase personnel morale and retention.

Reduce Injury Costs

Aside from the obvious negative impacts on personnel health and well-being, workplace injuries can also negatively affect operations by resulting in medical expenses, compensation claims, and lost productivity.

Preventing even a single serious injury can offset the cost associated with safety systems.

Minimize Aircraft Damage

Accidents, including cuts and burns involving avionics instruments, can lead to costly repairs and downtime. A fall while inspecting the aircraft or installing a cover can damage the wing, fuselage, or engine, leading to major repairs and extended downtime. And the most catastrophic cause of damage, aircraft crashes, can result in total loss of the aircraft.

Protective ground support equipment, such as avionics covers and engine shields, simultaneously protects aircraft and aviation personnel, including ground crews and pilots, by reducing on-the-ground injuries and in-flight incidents.

Improve Operational Efficiency

Injuries to personnel can reduce operational efficiency by causing delays, unplanned downtime, or loss of key personnel. For smaller operations, especially, a single injury to key personnel can cripple flight-readiness, resulting in unplanned downtime.

Safe environments reduce disruptions, delays, and rework, allowing personnel to perform tasks with greater confidence and focus.

Raise Reputation and Credibility

Strong safety standards and low incident rates can increase an organization’s reputation and credibility amongst its workforce and customers.

Increase Personnel Morale and Retention

Personnel who feel that their safety is prioritized are more engaged, more productive, and more likely to remain with the organization.

Engineering & Building Risk Mitigation

One of the most effective approaches to risk mitigation and hazard elimination is the effective design and engineering of protective aircraft equipment, including avionics covers and engine shields. Poorly designed equipment increases the risk of injury and is less likely to be implemented. Well-designed equipment not only protects the aircraft but also mitigates the risk of injuries, falls, strains, and aircraft accidents.

Safety-Driven Design

Protective aircraft ground support equipment should be designed to mitigate the risks associated with real-world conditions, including low visibility, extreme temperatures and weather, high winds, time pressure, and noisy or chaotic environments.

Key features of safety-driven design that mitigate the risk of these conditions include visibility, ease of use, and durability.

Design elements that increase visibility include the use of bright colors, reflective or highcontrast elements, clear markings, and remove-before-flight warning streamers. By enhancing visibility, these elements reduce accidental contact with sensitive instruments, decreasing the risk of aircraft damage or personnel injury, and ensuring covers are properly removed. Additionally, integrated lanyard systems can boost visibility and serve as an additional reminder to remove covers before flight.

Easy-to-use aircraft protective ground support equipment is far more likely to be consistently implemented and correctly deployed. Features that increase ease of use include ergonomic design, lightweight construction, quick and simple deployment, and pole installation. Ergonomic design enables gloved hands to grip and carry equipment, while traditional PPE enhances personnel protection. Lightweight construction reduces strain and fatigue. Quick and simple deployment increases operational efficiency, and pole installation keeps personnel off ladders, lifts, and wings, reducing the risk of falls.

Durability is not only key to ensuring aircraft are protected from foreign object debris and damage, but also to protecting personnel. High-temperature covers will not melt but canhelp shield personnel from heated avionics instruments. Additionally, proper aircraft protection enhances in-flight safety for in-flight personnel, including pilots and flight crews.

Safety-Driven Craftsmanship

Safety-driven craftsmanship is a foundational principle for our team. Our covers - whether for engines, pitot probes, or other avionics instruments - serve as the first line of defense against environmental damage and foreign object intrusion. As such, their production demands a meticulous commitment to quality, precision, and awareness of foreign object debris.

Quality begins with material selection. By sourcing only the highest-quality materials available, we build our aviation ground support products to stand the test of time, withstand the elements, and continually push our industry forward.

Precision is vital to ensure covers provide a snug and secure fit. Each cover must meet exact specifications, as even minor deviations can compromise its effectiveness. Too loose, and they may detach or allow contamination; too tight, and they can be difficult to install and remove, or damage sensitive components. Precision is especially important for engine protection, as engine shape and dimensions vary widely across models. At Sesame, we’ve developed unique quality assurance measures tailored to the aviation industry, including our SPIDER Precision Fit System.

At Sesame, quality assurance measures include multiple in-process quality inspections at every stage of production, as well as a final quality inspection before the product ships.
