Airworthiness Directive · Amendment 39-15410 · Eurocopter France Model EC130 B4 Helicopters
Eurocopter France Model EC130 B4 Helicopters
Model EC130 B4 helicopters not modified per MOD 073572, with the battery in either the right-hand baggage compartment or the tailboom, certificated in any category.
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.
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, do the following:
(a) Modify the wiring of the battery overheat sensing circuit and test the battery overheat sensing indicator light by following the Accomplishment Instructions, paragraph 2.B.1. or 2.B.2., depending on the location of the battery, of Eurocopter Alert Telex No. 24A001, dated December 20, 2005.
(b) Modifying and testing the battery overheat sensing circuit by following paragraph (a) of this AD is terminating action for the requirements of this AD.
(c) To request a different method of compliance or a different compliance time for this AD, follow the procedures in 14 CFR 39.19. Contact the Manager, Rotorcraft Directorate, FAA, ATTN: Carroll Wright, Aviation Safety Engineer, Regulations and Policy Group, Fort Worth, Texas 76193-0111, telephone (817) 222-5120, fax (817) 222-5961, for information about previously approved alternative methods of compliance.
(d) Modifying the wiring of the battery overheat sensing circuit and testing the battery overheat sensing indicator light shall be done in accordance with the specified portions of Eurocopter Alert Telex No. 24A001, dated December 20, 2005. The Director of the Federal Register approved this incorporation by reference in accordance with 5 U.S.C. 552(a) and 1 CFR part 51.
