Airbus Planes Told to Move a Harness

## Summary

The FAA wants to fix a safety issue on certain Airbus Canada airplanes where a hydraulic pump harness is too close to the plane’s structure, which could cause problems. They’re proposing a simple fix to move the harness and keep flights safe. Owners need to comment by August 13, 2026, and the fix might cost some time and money but keeps everyone flying worry-free.

## Abstract

The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Canada Limited Partnership Model BD-500-1A10 and BD- 500-1A11 airplanes. This AD was prompted by the discovery of a low clearance condition between a hydraulic motor pump harness and the airplane structure at the aft fuselage between certain frames, which was found during final airplane assembly. This proposed AD would require modification of the harness installation. The FAA is proposing this AD to address the unsafe condition on these products.

## Effects PRIA read

- Required harness modification for safety: benefit, high. If you operate Airbus Canada Model BD-500-1A10 or BD-500-1A11 airplanes, the FAA proposes a rule requiring you to modify the hydraulic motor pump harness installation by adding a clamp support on the bracket between fuselage frames FR 80 and FR 81 as specified in Transport Canada AD CF-2025-18 (dat…
- Compliance cost per airplane estimated: cost, low. The FAA estimates the modification will take 1 work-hour at $85 plus $27 in parts, for a total cost of $112 per airplane. The FAA estimates this proposed AD would affect 101 U.S.-registered airplanes, for a total estimated cost to U.S. operators of $11,312.
