ADDRESSES: FOR FURTHER INFORMATION CONTACT: SUPPLEMENTARY INFORMATION: REGULATORY TEXT: 76-09-11 LOCKHEED: Amendment 39-2601 as amended by Amendment 39-2615. Applies to all Model 382 series airplanes below serial number 4673. Before further flight, unless already accomplished, perform the crank arm inspection for rudder, aileron and elevator in accordance with Lockheed Alert Service Bulletin A 382-27-17. If the crank arms do not pass the inspection requirements, replace the crank arm or servo valve assembly prior to further flight. The Lockheed Alert Service Bulletin stated that acceptable replacement cranks were identified with a "V" index mark. However, some of the replacement cranks are being made from a different material than those identified with a "V" index mark. These new cranks are identified with a straight line index mark and either of the cranks identified with a "V" or a straight line index mark are acceptable. Amendment 39-2601 was effective May 14, 1976 and was effective on receipt for all recipients of the telegram dated April 23, 1976, which contained this amendment. This Amendment 39-2615 becomes effective immediately. FOOTER:
