Airworthiness Directive · Amendment 39-16440 · Doors
GROB-WERKE (Type Certificate Previously Held by BURKHART GROB Luft- und Raumfahrt) Models G115C, G115D and G115D2 Airplanes
This AD applies to GROB-WERKE (Type Certificate Previously Held by BURKHART GROB Luft- und Raumfahrt) Models G115C, G115D, and G115D2 airplanes, all serial numbers, certificated in any category.
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
Unless already done, do the following actions:
(1) Before further flight after November 1, 2010 (the effective date of this AD), fabricate a placard (using at least 1/8-inch letters) with the following words and install the placard on the instrument panel within the pilot's clear view: “AEROBATIC FLIGHT PROHIBITED.”
(2) Before the next aerobatic flight after November 1, 2010 (the effective date of this AD), do a canopy jettison test following Grob Aircraft AG Service Bulletin No. MSB1078-164, dated July 21, 2009.
(3) If the canopy jettison fails the test required in paragraph (f)(2) of this AD, before further aerobatic flight, contact Grob Aircraft AG, Customer Service, 86874 Tussenhausen-Mattsies, Germany, telephone: + 49 (0) 8268-998-105; fax; + 49 (0) 8268-998-200; e-mail: productsupport@grob-aircraft.com, for an FAA-approved repair scheme and incorporate the repair scheme.
(4) Within 7 days after doing the canopy jettison test required in paragraph (f)(2) of this AD or within 7 days after November 1, 2010 (the effective date of this AD), whichever occurs later, submit a report of the test results using Appendix 1 of Grob Aircraft AG Service Bulletin No. MSB1078-164, dated July 21, 2009, to Grob Aircraft AG at the address specified in paragraph (f)(3)(i) of this AD.
(5) After the corrective actions specified in paragraph (f)(3) or if the canopy jettison passed the test required in paragraph (f)(2) of this AD, before further flight, remove the placard that was installed in accordance with paragraph (f)(1) of this AD.
Note: This AD differs from the MCAI and/or service information as follows: The MCAI does not have a placard requirement. To eliminate any confusion and to ensure pilot awareness of the unsafe condition, we added a temporary placard requirement to this AD.
