Passenger Stairs and Boarding Bridges: Maintain the Access Route
Passenger access equipment needs inspection and service appropriate to its manufacturer and operating environment. Maintenance should cover the full route, including transitions and controls.

Inspect the complete passenger access route
Passenger stairs and boarding bridges should be maintained as complete access arrangements. Review walking surfaces, rails, movement restraints, controls and positioning functions where fitted. Record damaged or changed behavior through the approved process. An intact rail does not compensate for a worn step surface or unreliable positioning mechanism.
Review the aircraft-facing interface in the approved configuration. Sill height is only one part of fit; transitions, clearances and aircraft state also matter. Coordinate positioning and removal with the responsible ground team. Do not make informal adjustments to conceal an incompatible interface or assume previous use beside another aircraft establishes suitability.
Keep repair and return status traceable
Use the actual manufacturer's cleaning, lubrication and repair information. A readily available nonslip coating or similar-looking replacement part should not be assumed suitable for every assembly. Identify the equipment, affected component, reported fault and work performed so maintenance completion is connected to the original issue.
Keep return-to-service responsibility clear and review changed operating conditions before use. For replacement equipment, specify the complete aircraft interface and positioning requirements along with the walking route. This supports reliable passenger access without treating a general maintenance checklist as approval for a damaged or mismatched installation.
| Check | Record | Purpose |
|---|---|---|
| Route | Steps, platforms, rails and transitions. | Complete walking-path condition. |
| Function | Wheels, restraints and controls as fitted. | Operation beyond appearance. |
| Interface | Aircraft and positioning configuration. | Verified access and clearance. |
| Service | Approved work and return decision. | Traceable repair and use status. |

Buyer questions
Can any nonslip coating repair a worn stair surface?
Use an approved method for the actual equipment and material. A coating can affect drainage, surface behavior or compatibility and should not be chosen solely by appearance. Follow the manufacturer's information and the responsible repair and return-to-service process for the specific condition.
Does correct aircraft fit justify using a faulty stair assembly?
No. Equipment condition and interface suitability are separate requirements. Resolve defects through the approved process and review positioning as required. A stair assembly that appears to align with the aircraft is not thereby cleared to operate with a failed lock, control or walking surface.
