Airworthiness Directive 2009-07-13
one-timeAirworthiness Directives; MD Helicopters, Inc. Model MD900 (including the MD902 Configuration) Helicopters
What this AD requires
This amendment adopts a new airworthiness directive (AD) for the specified MD Helicopters, Inc. (MDHI) model helicopters that requires, within 30 days, reducing the current gross weight limit to a maximum gross weight limit of 5,400 pounds and inserting a copy of this AD into the Limitations section of the Rotorcraft Flight Manual (RFM) or making certain optional modifications that constitute terminating actions. This amendment is prompted by flight tests that show that the information currently listed in the Limitations section of the RFM is inconsistent with the actual performance of the helicopter. The actions specified by this AD are intended to prevent loss of directional control of the helicopter.
Which aircraft AD 2009-07-13 applies to
Applies only to helicopters (including MD902 Configuration) that have not complied with MD Helicopters, Inc. (MDHI) Mandatory Service Bulletin SB900-099 R1, dated December 27, 2006.
Whether AD 2009-07-13 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.
