Models named: EC 155B. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
Model EC 155B helicopters, certificated in any category.
Compliance
Required as indicated, unless accomplished previously. To prevent failure of the caution advisory display (display) to warn of an engine governor failure, resulting in an engine over speed, loss of an engine, and subsequent loss of control of the helicopter, accomplish the following: (a) Before further flight, on ground run-up, with both engines running: (1) Determine if the red “GOV” warning light on the front panel of the caution display for the No. 1 engine comes on when you operate the Engine No. 1 governing mode selector. (2) Set the selector back to the NORMAL or to the AUTO position and close the cover. (3) Repeat this check on engine No. 2. (4) If the display panel illuminates the “GOV” warning lights during the No. 1 and No. 2 engine checks, the panel is operating properly. (b) An owner/operator (pilot), holding at least a private pilot certificate, may perform the visual check and must enter compliance with paragraph (a) of this AD into the helicopter maintenance records in accordance with 14 CFR sections 43.11 and 91.417(a)(2)(v)). Note 1: Eurocopter Alert Service Bulletin EC155 No. 77A001, dated May 7, 2003, pertains to the subject of this AD. (c) If red crosses appear on the upper line on the front panel of the display instead of the “GOV” warning lights, before further flight, replace the front panel with an airworthy front panel, part number (P/N) 022TA0402. (d) Replacing the front panel of the display with an airworthy front panel, P/N 022TA0402, constitutes terminating action for the requirements of this AD. (e) 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 Safety Management Group, Rotorcraft Directorate, FAA, for information about previously approved alternative methods of compliance. (f) Special flight permits will not be issued. (g) This amendment becomes effective on October 14, 2003. Note 2: The subject of this AD is addressed in Direction Generale De L'Aviation Civile (France), AD No. 2003-196(A), dated May 28, 2003.
