Plain English Summary

3/10 complexity

This airworthiness directive requires operators of Skyvan MK 3, 3A, 3M and Skyliner aeroplanes to inspect the main landing gear brake flanges using the fluorescent penetrant method, following Dowty Mandatory Service Bulletin (MSB) 32-10M Revision 3. Initial inspection must occur before the MSB-specified thresholds or before 17 September 1995 (whichever is later), and re-inspections are required every 1,000 landings. The AD links an increased gear service life to compliance, so operators pay for inspections, record-keeping and any remedial work (Requirement; Compliance; Re-inspect; Background).
