NOTES
NOTE 1. Current weight and balance report including list of equipment included in certificated empty weight
and loading instructions must be in each helicopter at time of original airworthiness certification
and at all times thereafter. Refer Operations Manual (TM 55-1520-221-10 or TM 1-1520-236-10)
or Appendix D of Maintenance Manual (TM 55-1520-221-23 or TM 55-1520-236-23) for CG
determination and use of ballast if required.
NOTE 2. EXTERNAL LOAD OPERATION
In accordance with Federal Aviation Administration approved BLR Aerospace, LLC Model
AH-1 Rotorcraft Flight Manual Supplement.
NOTE 3. (a) FAA Airworthiness Directives for all Lycoming engines T53-L-13 (T53-L-13) or T53-L-703
series must be reviewed for applicability and complied with accordingly.
(b) This type certificate may not be used by any other person or entity without written permission
from the type certificate holder.
NOTE 4. These model helicopters must be serviced, repaired and maintained in compliance with TM 55-1520-
221-10, TM 1-1520-234-10, or TM 1-1520-236-10 and TM 55-1520-221-23, TM 55-1520-234-23, or
TM 55-1520-236-23, or BLR Instructions for Continued Airworthiness BLR-AH1-950. Component
overhaul intervals and replacement time shall be in accordance with the TBO/Replacement Schedule
found in TM 55-1520- 221-23, TM 55-1520-234-23, TM 55-1520-236-23, or BLR-AH1-950 unless
superseded by appropriate Airworthiness Directive.
NOTE 5. Special Inspection Requirements:
Refer to Garlick Helicopters, Inc., Drawing No. GH-005 for instructions on 50-hour visual inspection
of the Lift Beam Assy. P/N 209-030-141.
NOTE 6. Torque pressure output by the engine torque sensing system varies with individual engines. A
calibration of this value is required on each engine and the value corresponding to take-off power is
stamped on the engine data plate.
NOTE 7. Gas producer speeds as shown under “Engine Limits” are maximum permissible speeds. The gas
producer speed for rated power outputs varies with individual engines and must be determined
during engine calibration and stamped on the engine data plate. The rated gas producer speed
shown on the temperature limit placard installed on the instrument panel must correspond to the
data plate.
H10NM Page 5 of 5
NOTE 8. Maximum permissible exhaust gas temperature varies with ambient temperature as described in the
Operators Manual. Check engine EGT by use of Health Indicator Test (HIT) prior to take-off (see TM
55-1520-221-10, TM 1-1520-234-10 or TM 1-1520-236-10 and HIT Log for the aircraft).

holder and may be incorporated by the FAA Form 337.
NOTE 11. Any Alteration to the type design of this aircraft may require Instructions for Continued
Airworthiness (ICA’s). Changes to the Type Design by means of a Supplemental Type Certificate
(STC) requiring ICA’s or changes to existing ICA’s must be submitted and reviewed by the Fort
Worth Aircraft Evaluation Group (FTW-AEG). Type Design Changes by means of a Field
Approval that require ICA’s must have those ICA’s reviewed by the Flight Standards District Office
(FSDO) managing the Field Approval or the FTW-AEG.
