AD NUMBER: PL2007-26-51
MANUFACTURER: Eurocopter Deutschland
SUBJECT: Airworthiness Directive PL2007-26-51
SUMMARY: This Emergency Airworthiness Directive (EAD) is prompted by a report of a fatal accident involving the failure of a tail rotor control rod (control rod). This condition, if not corrected, could result in the failure of a control rod and subsequent loss of control of the helicopter.

The FAA has reviewed Eurocopter Alert Service Bulletin No. EC135-67A-017, dated December 13, 2007 (ASB). The ASB describes procedures for checking the attachment hardware on the control rod for tight fit, checking the ball pivot for damage and freedom of movement, and replacing any damaged part before the next flight.

The European Aviation Safety Agency (EASA) notified us that an unsafe condition may exist on Eurocopter EC135 and EC635 helicopters. EASA advises that an accident recently occurred with an EC135 helicopter in Japan. Preliminary investigation results indicate that the helicopter loss of control was due to the failure of the control rod.

EASA has classified the Eurocopter ASB as mandatory and issued EASA AD No. 2007-0301-E, dated December 13,2007, to ensure the continued airworthiness of these helicopters in Germany.
