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.
