Airworthiness Directive 99-11-10
one-timeAirworthiness Directives; Eurocopter France Model AS 332L2 Helicopters
What this AD requires
This amendment adopts a new airworthiness directive (AD) that is applicable to Eurocopter France Model AS 332L2 helicopters with a certain power-loss printed circuit board (PCB) installed. This action requires replacing that power-loss PCB with an airworthy power-loss PCB. This amendment is prompted by malfunctions discovered during environmental testing of the power-loss PCB conducted by the manufacturer. The actions specified in this AD are intended to prevent incorrect engine status indications, random activation of the maximum rotor revolutions-per-minute (RPM) alarm, and failure to reset the One- Engine Inoperative (OEI) logic after an actual loss of power from one engine.
Which aircraft AD 99-11-10 applies to
Power-loss printed circuit board (PCB) replacement AD to prevent incorrect engine-status indications, spurious max-rotor-RPM alarm, and failure to reset One Engine Inoperative (OEI) logic; replace PCB P/N SE01958 (Eurocopter France P/N 704A47720091), Amendment C or D, with airworthy PCB P/N SE01973 (Eurocopter France P/N 704A47720109). Specific helicopter model is not stated in the extracted applicability text; cross-referenced to DGAC (France) AD 98-290-011(A).
Whether AD 99-11-10 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.
