## The airworthiness directive

81-10-04 PIPER AIRCRAFT CORPORATION: Amendment 39-4094. Applies to Model PA-44-180 (Seminole), serial numbers 44-7995001 through 44-8095006, airplanes certificated in all categories.

Compliance is required within the next 50 hours time in service after the effective date of the AD, unless already accomplished. To reduce aileron spar deflection and cracking which could result in loss of aileron control, accomplish the following:

a. Modify the ailerons in accordance with Piper Aircraft Corporation Service Bulletin No. 702, dated December 4, 1980, and Piper Rework Kit P/N 764 088V.

b. Make appropriate maintenance record entry.

An equivalent method of compliance may be approved by the Chief, Engineering and Manufacturing Branch, FAA, Southern Region.

This amendment becomes effective April 30, 1981.
