Production Basis None. No helicopter may be produced under this approval. Prior to adding
serial numbers to this Type Certificate, each candidate helicopter must undergo
a conformity inspection. The conformity inspection will be conducted in
accordance with a Type Inspection Authorization, Part 1, or request for
conformity that will include as a minimum, the inspections contained in the
FAA Rotorcraft Directorate Restricted Category conformity document dated
September 25, 2001 or later FAA approved revisions.
Equipment Equipment necessary for the particular special purpose operation must be
installed.
NOTES
NOTE 1 A current weight and balance report including a list of equipment included in

iller Helicopters Engineering Report No. SH61002, NC, dated
January 7, 1998, or later FAA approved revision. The Engineering
R
eport also identifies the special purpose modification(s) accomplished
o
n that particular helicopter. The Engineering Report identifies
military airframe changes (AFC) accomplished on the helicopter. In
addition, each helicopter must pass an inspection for any possible
hidden damage and the military records reviewed for acceptability of
any repairs or alterations. Navy Airframe Change 450 (or equivalent
work instructions outlined in the Instructions for Continued
A
irworthiness) must be accomplished on the aircraft prior to
c
ertification.
(B) The maintenance, overhaul and modification records of each helicopter
must be reviewed for military changes that may affect the airworthiness
of the helicopter.

NOTE 14 Maximum continuous total power for two-engine operation is limited to 2100
hp.
NOTE 15 With two engines operating take-off power may exceed torque = 103% on one
engine to a maximum of torque = 123% provided that the torque on the other
engine is less than 103% and the sum of the individual torque values does not
exceed 206%.
Transient operation between 206% and 230% total torque is permitted for
periods of not over 5 seconds for each occurrence. Operation between 206%
and 230% total torque for more than 5 seconds or over 230% total torque for
any period requires removal and overhaul of the main gearbox.
With one engine operating transitory over-torque on the order of 150% Q is
permissible provided the over-torque period does not exceed 20 seconds per
application and the cumulative time above 135% Q does not exceed 30 minutes
during the transmission overhaul period. Torque values and duration above
135% must be recorded.

NOTE 16 If takeoff power (CT58-140-1 or CT58-140-2) is used in cumulative excess of 5
minutes during any one emergency, the engine must be inspected in accordance
