the Boeing Company Airplanes
This AD applies to The Boeing Company Model 787-8 airplanes, certificated in any category, line numbers 7 through 9 inclusive, 23, 24, 27, 29, 31, 33 through 35 inclusive, 37, 38, 40 through 42 inclusive, 44 through 72 inclusive, 74 through 78 inclusive, 80, 82 through 84 inclusive, 86, 87, 89, 92, 94 through 99 inclusive, 101, 102, 108, and 111.
We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 787-8 airplanes. This AD requires either removal or inspection of the Honeywell fixed emergency locator transmitter (ELT), and corrective action if necessary. This AD was prompted by a report of a fire involving a Honeywell fixed ELT. We are issuing this AD to prevent a fire in the aft crown of the airplane, or to detect and correct discrepancies within the ELT that could cause such a fire.
Within 10 days after the effective date of this AD, do the actions specified in either paragraph (g)(1) or (g)(2) of this AD.
(1) Remove the Honeywell fixed ELT using a method approved in accordance with the procedures specified in paragraph (h) of this AD.
(2) Inspect the Honeywell fixed ELT for discrepancies, and do all applicable corrective actions before further flight, using a method approved in accordance with the procedures specified in paragraph (h) of this AD.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
