Airworthiness Directive 2009-07-06
one-timeAirworthiness Directives; Hamilton Sundstrand Propellers Model 568F Propellers
What this AD requires
The FAA is adopting a new airworthiness directive (AD) for Hamilton Sundstrand Propellers model 568F propellers with certain part number (P/N) and serial number (SN) blades. This AD requires removing affected propeller blades from service for rework. This AD results from reports of blades with corrosion pits in the tulip area of the blades. We are issuing this AD to prevent cracks from developing in the tulip area of the blade, which could result in separation of the blade and loss of airplane control.
Which aircraft AD 2009-07-06 applies to
Applies only to model 568F propeller blades with the listed part numbers bearing a serial number listed in AD Table 1 (discrete SN list, not a continuous range: 31, 33, 34, 37, 40, 43, 105, 230, 259, 265, 277, 278, 403, 747, 1007, 1031, 1510, 1515, 1803, 1813, 1823, 1834, 1917, 2072, 2299, 2300, 2383, 2459, 2460, 2462, 2464, 2469, 2470, 2473, 2492, 2510, 2535, 2577, 2625, 20010731, 20010732, 20010917, 20020568), installed. Installed on, but not limited to, ATR-42-400/-500, ATR72-210A/-500, and CASA C-295 airplanes.
Whether AD 2009-07-06 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
