Fall Protection for Aircraft Hangars

Overhead fall protection for aviation inspection, maintenance & repair

Whether in the hangar or on flight line, aviation techs and mechanics often conduct their work well above the hangar floor and tarmac.  We offer a wide range of solutions designed specifically for performing inspection, maintenance, & repairs on fixed-wing and rotary aircraft.

Designed and installed for commercial, corporate, and military our systems can be found in MRO facilities all over the world. FLS systems meet OSHA 1910 and ANSI Z359 requirements and provide continuous and uncompromising safety while working at height on the aircraft.

Hazard Assessment & Structural Analysis

Flexible Lifeline Systems aircraft fall protection solutions start with evaluating the specific maintenance operations performed. In the case of hanger systems, evaluation of the supporting building structures is often required.

Engineering & Design

Our team of registered structural engineers, AutoCAD designers and field engineers model fall protection systems in relation to the aircraft position and hangar structure to provide the maximum coverage, compliance and safety.

Fabrication & Production

To maintain the highest level of quality, every system part and manufactured component is thoroughly inspected, processed and supplied in accordance with our ISO 9001:2015 program.

Construction & Installation

Our construction and field technicians have decades of experience working with aircraft and in hangar environments enabling us to perform safely and efficiently and complete even the most complicated process in days versus weeks.

User Training & Certification

Flexible Lifeline Systems coordinators, trainers, technicians, and engineers proactively ensure solutions are properly used, serviced, inspected and remain compliant with latest standards and regulations through annual recertification.

Aircraft Overhead Fall Protection Hanger Demo


Aircraft Fall Protection for U.S. Military

FLS engineered, fabricated and installed a total of twelve enclosed track and trolley systems capable of supporting three users each. FLS designed the safety systems at elevations below HVAC and fire protection equipment to prevent interference with other hangar systems.

Protecting Alaska Airlines MRO Staff

For this project, Flexible Lifeline Systems designed, engineered, and installed a total of six (6) Type 1 FlexRail systems. Each system was designed and engineered for a two (2) user fall arrest.

Wood-frame Aircraft Hangar Flexrail Retrofit

The FLS team devised a hybrid system, in which a very light-weight tube would be installed the full length of the cable system run. This tube acts as a compression strut along the entire length of the cable, and will distribute any fall arrest loads, both horizontal and vertical, without structural damage to the wood trusses.

Overhead Lifeline for Southwest Airlines

The Southwest Airlines maintenance team required the capability to add two 737-900 aircraft near the front of one of their hangars requiring the engineering of atypical support connections for the system anchor points.

Osha Regulations for Aircraft Fall Protection


1910.140(12) Anchors used to attach to personal fall protection equipment must be independent of any anchorage used to suspend employees or platforms on which employees work. Anchorages used to attach to personal fall protection equipment on mobile work platforms on powered industrial trucks must be attached to an overhead member of the platform, at a point located above and near the center of the platform.


1910.140 Personal Fall Arrest Systems: The employer must ensure that each personal fall protection system used must comply with the requirements in this section:

  1. Limit the maximum arresting force on the employee to 1,800 pounds; 1910.140(d)(1)
  2. Bring the employee to a complete stop and limit the maximum deceleration distance the employee travels to 3.5 feet; 1910.140(d)(1)
  3. Have sufficient strength to withstand twice the potential impact energy of the employee free falling a distance of 6 feet, or the free fall distance permitted by the system; and… 1910.140(d)(1)
  4. Sustain the employee within the system/strap configuration without making contact with the employee’s neck and chin area. 1910.140(d)(1)


In the absence of a specific requirement for Inspection, OSHA Sec 5.a.1 becomes default: OSHA Sec 5.a.1 (a) Each employer – (1) shall furnish to each of his employees employment and a place of employment which are free from recognized hazards that are causing or are likely to cause death or serious physical harm to his employees; 29 USC 654 (2) shall comply with occupational safety and health standards promulgated under this Act. (b) Each employee shall comply with occupational safety and health standards and all rules, regulations, and orders issued pursuant to this Act which are applicable to his own actions and conduct.

Following manufacturer’s requirements is considered a reasonable effort to satisfy this general rule and employee responsibility. Flexible Lifeline Systems follows the requirements set by the manufacturer of the components that are used to build your system. Additionally, ANSI Standards ANSI/ASSE Z359.2 Z.359.6-2016 9.2, while not codified as law, are considered to be “best practices” and often required by many companies – insurance, banking, etc., to provide coverage such as worker compensation or professional insurance, or to assess capital asset values. These standards speak directly to importance of regular inspection of fall protection systems.
