The airworthiness directive
79-09-02 CESSNA: Amendment 39-3453. Applies to Model 441 (Serial Numbers 441-0001 through 441-0090) airplanes.
COMPLIANCE: Required as indicated, unless already accomplished.
To assure proper drainage of the aileron control surfaces, within the next 100 hours time-in-service after the effective date of this AD, accomplish the following:
A) Incorporate additional drainage of the ailerons by drilling new drain holes in accordance with the instructions provided in Cessna Propjet Service Information Letter PJ 79-3, dated March 5, 1979.
B) Any equivalent method of compliance with this AD must be approved by the Chief, Engineering and Manufacturing Branch, FAA, Central Region.
NOTE: The FAA has determined that there is insufficient justification to require mandatory compliance with the elevator portion of Cessna Service Information Letter PJ 79-3. Therefore, this AD is not applicable to elevator drainage improvements provided by that letter.
This Amendment becomes effective May 7, 1979.
