Plain English Summary

2/10 complexity

Requires fitting safety wire to the roll pin linking the fuel‑selector rotor shaft to its yoke on Cessna 207 aircraft (serials 20700001–20700773), installed per Cessna SIL SE84‑5 before the next Maintenance Release after 31 May 1985.

The action prevents roll‑pin migration that can cause fuel‑selector loss and engine fuel starvation; owners/operators fund the one‑off work and the authorised maintenance organisation signs off compliance.

Applicability: Model 207 with S/Nos. 20700001 to 20700773. Requirement: Action in accordance with Cessna SIL SE84-5.

Note: FAA AD 85-02-07 refers.

Compliance: Prior to issue of the next Maintenance Release after 31 May 1985.
