Airworthiness Directive 2013-08-06
one-timeAirworthiness Directives; Bell Helicopter Textron Canada (Bell) Helicopters
What this AD requires
We are adopting a new airworthiness directive (AD) for Bell Model 430 helicopters, which requires replacing certain components of the air data system. This AD was prompted by the discovery of incorrect indicated airspeed when the helicopter was tested to the cold temperature limits (-40 degrees centigrade) required for Category A operations. The actions of this AD are intended to correct the published Vne and to correct the indicated airspeed.
Which aircraft AD 2013-08-06 applies to
S/N 49001 through 49103 with Overspeed Warning Kit P/N 430-706-004-101 or 430-706-004-103 installed; S/N 49001 through 49100 with Single Automatic Flight Control System (AFCS) with Flight Director Kit P/N 430-705-009-103/-105/-109/-111/-115/-117 or P/N 430-705-011-109/-111/-121/-123 installed; S/N 49001 through 49100 with Dual AFCS with Flight Director Kit P/N 430-705-011-103/-105/-115/-117/-125/-127/-129/-133/-135/-137 installed. Condition is inability to operate at published Vne indicated airspeeds within the cold temperature limits (-40 degrees centigrade) required for Category A operations.
Whether AD 2013-08-06 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.
