Compliance: Required as indicated, unless already accomplished. To prevent the failure of the magnesium elevator control fittings, accomplish the following: (a) Within 100 hours time-in-service (TIS) after the effective date of this AD, determine the composition of the elevator control fittings in accordance with the instructions contained in Beech Service Bulletin No. 2242, Revision 1, dated August 1988. (1) If the fittings are determined to be aluminum, no further action is required by this AD. (2) If the fittings are determined to be magnesium, accomplish the actions specified below. (b) At the time of the inspection per paragraph (a), and every 100 hours TIS thereafter, visually inspect each magnesium elevator control fitting for cracks in accordance with the above referenced Service Bulletin. (c) If any fitting is found to be cracked, prior to further flight replace the cracked fitting with an aluminum fitting as described in the above referenced Service Bulletin. (d) The above inspections are no longer required when aluminum fittings have been installed on both elevators. (e) Airplanes may be flown in accordance with FAR 21.197 to a location where this AD may be accomplished. (f) An equivalent means of compliance with this AD may be used if approved by the Manager, FAA, Wichita Aircraft Certification Office, 1801 Airport Road, Room 100, Mid-Continent Airport, Wichita, Kansas 67209; Telephone (316) 946-4400.

Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model. - [NTSB SEA02LA116](https://openairdocs.org/ntsb/SEA02LA116), Jun 21, 2002: Beech G35 (N4647D), Yakima, WA, substantial damage. Probable cause: Empennage flutter which resulted in structural damage during descent for landing. Turbulence was a factor. - [NTSB CHI98LA125](https://openairdocs.org/ntsb/CHI98LA125), Apr 13, 1998: Beech B35 (N5246C), Bentonville, AR, substantial damage. Probable cause: the damage to the empennage was due to flutter. --- OpenAirDocs.org is an independent research project of [Contrail Labs](https://contraillabs.com/).
