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) Within the next 25 hours time-in-service (TIS) after January 3, 2008 (the effective date of this AD) or within the next 6 calendar months after January 3, 2008 (the effective date of this AD), whichever occurs first, inspect the welded parts of the flight control system for any cracks, deformations, or distortions following Grob Aerospace Service Bulletin No. MSB 306-35, dated April 27, 2007. Thereafter, repetitively inspect at intervals not to exceed 12 calendar months.
(2) If you find any cracks, deformations, or distortions as a result of any inspection required by paragraph (f)(1) of this AD, before further flight, replace the affected part following Grob Aerospace Service Bulletin No. MSB 306-35, dated April 27, 2007.
