## The airworthiness directive

76-07-01 FAIRCHILD AIRCRAFT: Amendment 39-2562. Applies to Models F-27 series and FH-227 series aircraft.

Compliance required as indicated:

To detect loose studs which may create a hazard, accomplish the following:

  (a) Within the next 200 hours time in service after the effective date of this AD, unless already accomplished within the last 1000 hours in service, inspect, clean and torque studs on terminal board assembly P/N 27-746011-11 to 100 inch-lbs.

  (b) Within the next 1800 hours replace the existing terminal block assembly with an MS 27212 terminal block assembly unless already accomplished. Fairchild Service Bulletin Nos. FH-227-24-11 and F-27-24-15, dated March 1, 1976, covers the replacement of the terminal block.

  (c) Upon request of the operator, an FAA Maintenance Inspector, subject to prior approval of the Chief, Engineering and Manufacturing Branch, FAA Eastern Region, may adjust the compliance times specified in this AD if the request contains substantiating data to justify the increase for that operator.

Fairchild Service Letter Nos. F-27-646 and FH-227-24-17, dated January 26, 1976, pertain to this subject.

This amendment is effective April 2, 1976.
