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). NOTE 9. All FAA Airworthiness Directives affecting this Type Certificate must be complied with; applicable Airworthiness Directives are listed in BLR-AH1-007. NOTE 10. In the furtherance of safety and continued airworthiness, Military M.W.O.'s (Military Service Bulletins) and model type improvements will be reviewed for applicability by the Type Certificate 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. --------------------------- END -------------------------- ``` ## ADs (2, in force first) - [AD 2024-19-17](https://openairdocs.org/ad/2024-19-17): Rotorcraft flight control · Airwolf Aerospace, LLC Tension-Torsion Strap Assemblies, P/N… (STC SR03408CH).
