Airworthiness Directive 99-13-03
one-timeAirworthiness Directives; Bell Helicopter Textron Canada (BHTC) Model 206L-4 Helicopters
What this AD requires
This amendment adopts a new airworthiness directive (AD) that is applicable to BHTC Model 206L-4 helicopters. This action requires a reduction in the retirement lives of certain collective idler links and collective levers, and re-identifying certain collective idler links and collective levers. This amendment is prompted by the discovery of two types of collective idler links and collective levers--manufactured from different materials--that are identified with the same part numbers but should have substantially different retirement lives. The actions specified in this AD are intended to prevent use of a collective idler link (link) or collective lever (lever) beyond its retirement life, which could lead to failure of the link or lever and subsequent loss of control of the helicopter.
Which aircraft AD 99-13-03 applies to
Collective idler link / collective lever retirement-life AD; actions per Bell Helicopter Textron Alert Service Bulletin No. 206L-98-110, dated May 6, 1998. Re-identified link P/N 206-010-446-107FM and lever P/N 206-010-447-109FM carry the same retirement lives as the original P/Ns 206-010-446-107 and 206-010-447-109.
Whether AD 99-13-03 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
