Rotorcraft Maintenance Manual

NOTE:
The overtorque is recorded in the excee­
dance log data from the integrated instru­
ment display system (IIDS).
The torque values shown in the IIDS data
log are in the P&WC engine torque scale.
To get the equivalent transmission torque
value, multiply the engine torque by
1.242.
Under some overtorque conditions, time at
overtorque must be recorded in the Rotorcraft
Log Book:
Record single engine operation overtorque
time as
S1 .
Record twin engine operation overtorque
time as
T1 .
Maximum overtorque total time is 5 hours . If
S1 + T1 = 5 hours , main rotor transmission
must be overhauled.
5. Overspeed
Overspeed is an incident in which the rotor
speed (N
R
) is more than the limits shown in
the applicable Rotorcraft Flight Manual. Use
the inspection schedules in Table 211 thru
Table 216 when there has been an overspeed.
NOTE:
The overspeed is recorded in the excee­
dance log data from the IIDS.
6. Lightning Strike
When you think there has been a lightning
strike on the helicopter, speak to the Field
Service Department at MDHI, Mesa, Arizona.
Telephone 1-800-388-3378 or (480)
346-6387. DATAFAX: (480) 346-6813 for
inspections and maintenance procedures you
need to do.
7. Engine Out/Low Rotor Functional Check
When major maintenance or a modification
has been done to the helicopter electrical
system, do the “Engine Out/Low Rotor Check”
(ref. the latest revision of the applicable
Rotorcraft Flight Manual (RFM)).
8. Unscheduled, Conditional Inspection
Tables
(Ref. Table 201 thru Table 216)
The tables for each inspection program/re­
quirement are divided into four columns:
The first column (Model) shows the model of
helicopter the inspection or procedure is
applicable to.
NOTE:
The MD900 is the only model listed in
the Type Certificate Data Sheet (H19HM).
The 902 is a configuration difference (ref.
Section 01-00-00, Aircraft Configuration).
The second column (Requirement) has a
short description of the necessary inspection
or procedure.
The third column (Ref. RMM Section) shows,
if applicable, the manual or section that has
the specific inspection or procedure.
The fourth column (Initial) is for personnel
to show they have done the necessary
inspection or procedure.
All completed inspection schedules must be
kept as a permanent part of the helicopter
records.
