AD NUMBER: 2004-14-22
MANUFACTURER: Pratt & Whitney
SUBJECT: Airworthiness Directive 2004-14-22
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for
Pratt & Whitney Canada (PWC) PW206B engines that have
incorporated PWC Service Bulletin (SB) No. 28119, and PW206C,
PW206E, PW207D, and PW207E turboshaft engines. This AD requires
checking the automatic low-cycle-fatigue (LCF) counting data made
by the engine Data Collection Unit (DCU) on installed engines, and
validating proper DCU automatic LCF counting before an engine is
installed. This AD results from two reports of irregular LCF
counting, observed between engines on the same helicopter, during
weekly recording of LCF data in the engine log books. We are
issuing this AD to prevent critical rotating parts from exceeding
published life limits, which could result in uncontained engine
failure and possible loss of the helicopter.The FAA is adopting a
