AD NUMBER: PL2003-03-18 MANUFACTURER: Raytheon SUBJECT: Airworthiness Directive
PL2003-03-18 SUMMARY: This amendment adopts a new
airworthiness directive (AD) that applies to all Raytheon Aircraft
Company (Raytheon) Beech Models 1900, 1900C, and
1900D airplanes. This AD requires you to perform
control column sweep and stop bolt inspections to verify full
elevator travel to the primary up and down stops and that the stop
bolt length is not excessive, re-rig the elevator control system if
the airplane does not pass the control column sweep and stop
inspections, and do a more detailed inspection at a later time if
the airplane does pass the inspection. This AD also requires you to
report the results of certain inspections. This AD is the result of
recent ground testing and a review of the rigging procedures of a
Raytheon Beech Model 1900D airplane, which reveals that the
elevator control system could be mis-rigged to restrict
elevator travel if current maintenance procedures are not properly
followed. In these instances, it may appear to the crew that they
have full elevator control column movement. However, the elevator
may not have full travel. Such restricted travel may remain
undetected until the airplane is operated in a loading condition
that requires full elevator authority to control the pitch. The
actions specified by this AD are intended to detect and correct any
mis-rigged elevator control system, which could lead to
insufficient elevator control authority and loss of control of the
airplane.
