Plain English Summary

1/10 complexity

This directive mandates a safety inspection for Short SC7 Skyvan Series 3 aircraft (a twin-turboprop utility plane).

What needs to be done:

Inspect the locknuts (special nuts that prevent bolts from loosening) on the aileron control rods located between wing stations 177 and 184, accessible via panel W1-16
Check specifically for "wire locking" — this is safety wire threaded through the nut and bolt to prevent them from vibrating loose

If the locknuts are not secured:

They must be wire-locked following the procedure in Short Information Letter No. 7
Using thread sealant like "Locktite" is specifically prohibited as a substitute for wire locking

Who must comply: All owners and operators of Short SC7 Series 3 models

Deadline: Within 100 hours of flight time after 25 November 1969
