Airworthiness Directive 2008-05-16
one-timeAirworthiness Directives; Eurocopter France Model EC130 B4 Helicopters
What this AD requires
This amendment adopts a new airworthiness directive (AD) for Eurocopter France (ECF) Model EC130 B4 helicopters that requires, within 110 hours time-in-service (TIS), modifying and testing the wiring of the battery overheat sensing circuit. This amendment is prompted by a malfunction in the battery overheat sensing circuit found during a scheduled inspection. The actions specified by this AD are intended to correct the connection of the thermal switch to the cockpit indicator light, to notify the flight crew of an overheated battery, and to prevent a thermal runaway of the battery, an in-flight fire, and subsequent loss of control of the helicopter.
Which aircraft AD 2008-05-16 applies to
Applicability depends on the aircraft’s type certificate — check it against the specific tail.
Whether AD 2008-05-16 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.
