Torque wrenches:
Torque wrenches should be of good quality and calibration must be
verified every 90 days to ensure accuracy.
Application of torque wrench loads:
Recommended tightening torque values and minimum drag torque
values for fine and coarse thread nuts, and minimum breakaway
torque for used self-locking bolts or screws are specified in Basic
HMI Section 2.
7-42. HOURMETER INSTALLATIONS
One standard and two optional hourmeter installations are offered on
the Model 269D Helicopter.
In the standard hourmeter installations, the hourmeter is actuated by
main transmission oil pressure. The hourmeter will run and record
time whenever the main rotor transmission oil pressure is above the
minimum value (main rotor turning, warning light out). When this
installation is utilized, no multiplying factor is required when the re-
corded time is used to determine periodic inspection requirements
overhaul intervals, and the service life of life limited components.
In the optional landing gear actuated hourmeter installation, the
hourmeter is actuated by a “squat” switch attached to the landing
gear. The hourmeter will run and record time whenever the aircraft
is in flight (no weight on the landing gear). This installation records
“flight time”, or “time in service” as defined in FAR Part 1.1, and
NO multiplying factor is required when this recorded time is used to
determine periodic inspection requirements, overhaul intervals, and
the service life of life limited components.
