The FAA has issued a Notice Of Proposed Rule Making to address concerns about brake fires in some Cirrus SR20 and SR22 aircraft. Four brake fires and two reports of airplanes losing directional control have been recorded, the FAA said. Cirrus issued Service Bulletins in December and January to address the problem. The bulletins required owners to upgrade the brakes and modify the fairings to make it easier to monitor brake temperatures. The proposed AD would also require the replacement of brake calipers or piston O-ring seals. The cost of compliance, the FAA estimates, could be up to about $2,700 if brake calipers need to be replaced. Comments are invited and must be received by the FAA by July 10.
NPRM Addresses Cirrus Brake Fires
Key Takeaways:
- The FAA has proposed an Airworthiness Directive (AD) for Cirrus SR20 and SR22 aircraft to address multiple reported brake fires and incidents of losing directional control.
- This proposed AD would require the replacement of brake calipers or piston O-ring seals, building on earlier service bulletins from Cirrus that mandated brake upgrades and fairing modifications.
- The estimated cost of compliance for the proposed AD is up to $2,700 per aircraft if brake calipers need replacement, with the FAA inviting public comments until July 10.
