REGULATORY TEXT:  
79-24-05 EMPRESA BRASILEIRA de AERONAUTICA, S.A. (EMBRAER): Amendment 39-3619. Models EMB-110P1 and EMB-110P2, certificated in all categories.

Compliance is required within the next 50 hours time in service, unless already accomplished, and thereafter at intervals not to exceed 250 hours time in service.

To prevent failure of the flap supports and possible loss of the flaps, accomplish the following:

A. With the wing flaps extended, using a 10-power magnifying glass or dye- penetrant method, conduct an inspection of all the flap supports, part numbers listed below, installed on the wing and on the flaps, for cracks in the components near the attachment bolts.


Flap Support Part Numbers
4A-2611.46.01
4A-2621.46.01
4A-2611.47.01
4A-2611.48.01
4A-2621.48.01
4A-2116.01.01
4A-2116.02.01 or 4A-2116.02.01N
4A-2216.02.01 or 4A-2216.02.01N
4A-2116.03.01
4A-2216.03.01

If any cracks are found, replace the component before further flight.

B. Upon request of the operator, an FAA maintenance inspector, subject to prior approval of the Chief, Engineering and Manufacturing Branch, Southern Region, may adjust the inspection interval if the request contains substantiating data to justify the increase for that operator.

C. Compliance with the provisions of this AD may be accomplished in an equivalent manner approved by the Chief, Engineering and Manufacturing Branch, Southern Region.

This amendment is effective November 21, 1979.
