Unsafe Condition
Malfunction of the flap operating system due to restricted freedom of movement in the universal joint pins or bolts of the wing flap connecting shaft assembly (P/N 27-727944-1).
AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Inspect the universal joint at each end of the wing flap connecting shaft assembly (P/N 27-727944-1) to ensure freedom of movement in all axes. Remove and replace deficient universal joint pins or bolts before further flight if movement is not determinable. Report findings to the FAA Eastern Region as specified.

ADDRESSES: FOR FURTHER INFORMATION CONTACT: SUPPLEMENTARY INFORMATION: REGULATORY TEXT: 69-20-07 FAIRCHILD-HILLER: Amendment 39-857 (Amendment 39-845 was not distributed.) Applies to Fairchild Hiller F-27 and FH-227 type airplanes certificated in all categories. To prevent malfunction of the flap operating system accomplish the following within 15 hours time in service after the effective date of this airworthiness directive unless already accomplished within the last 25 hours time in service, and thereafter when the universal joint pins or bolts at either end of the subject connecting shaft assembly are removed: (a) Inspect the universal joint at each end of the wing flap connecting shaft assembly, P/N 27-727944-1, located between the flap motor gearbox at wing station 141 left (installed in the wheel well of the left nacelle) and the gearbox at wing station 121 left to assure some freedom of movement in all axes. If freedom of movement is not determinable, remove and replace deficient universal joint pin or bolt before further flight except that a ferry flight may be permitted without the use of flaps in accordance with FAR 21.197. (b) Report the results of the findings in compliance with this AD to the Chief, Engineering and Manufacturing Branch, FAA Eastern Region (reporting approved by the Bureau of the Budget under BOB No. 04-R0174). This amendment is effective October 3, 1969 and was effective upon receipt for all recipients of the telegram dated 3 September 1969 which contained this amendment. FOOTER:
