What to do
Operators of Bell 505 helicopters with serial number 65011 and later must inspect the tail cone assembly identification plate within 330 flight hours or 6 months from 26 January 2026, whichever occurs first. If the plate shows part numbers SLS-030-600-023 or SLS-030-600-025, it must be replaced with a correct identification plate following Bell Alert Service Bulletin 505-25-47 or later approved revisions.
Summary
EASA Airworthiness Directive CF-2026-01 is issued for Bell Helicopter Textron Canada Limited model 505 helicopters, serial number 65011 and subsequent. It addresses an issue with incorrect part number identification plates on certain tail cone assemblies. The directive mandates corrective action to ensure accurate part number identification to maintain aircraft safety.
What changed
This new airworthiness directive introduces a requirement to replace incorrect tail cone assembly identification plates that display wrong part numbers SLS-030-600-023 or SLS-030-600-025. The replacement plates must show the correct part number as specified in Bell Alert Service Bulletin 505-25-47 or later approved revisions.
Why it matters
Accurate part number identification on tail cone assemblies is critical to ensure compliance with life limits and prevent fatigue cracking of the tailboom. Failure to correct the identification plate could lead operators to mistakenly believe the tail cone assembly has unlimited life, risking structural failure and loss of aircraft control. This directive helps operators and maintenance teams maintain airworthiness and safety standards.
