(see Note 7) Special Conditions: No. 27-035-SC Robinson Model R66 Helicopter, Sec. 27.1309, Installation of HeliSAS Autopilot and Stabilization Augmentation System (AP/SAS). No. 27- 057-SC Robinson Model R66 Helicopter, Pressure Refueling Provisions. TC Application Date: September 06, 2006. TC Issue Date: October 25, 2010. The R66 is approved for day and night VFR operations only. Production Basis Production Certificate No. 424WE dated October 25, 2010. Equipment The basic required equipment as prescribed in the applicable airworthiness regulations (see Certification Basis) must be installed in the aircraft for certification. In addition, the following FAA -approved Rotorcraft Flight Manual is required: R66 Pilot’s Operating Handbook and FAA Approved Rotorcraft Flight Manual (RTR 661) dated October 25, 2010, or later approved revision. Other Limitations and Conditions Any modification made to the interior configuration or exterior lighting of helicopters placarded as Night Vision Goggle (NVG) compatible invalidates the NVG compatibility. The aircraft is not approved for NVG operations until an official re -evaluation is completed and the modified aircraft is found to be compliant with NVG requirements. For helicopters equipped with a laser designator, laser operation is not FAA - approved for civil aircraft operations. Laser us age is restricted to public -use operations. For civil aircraft operations the laser must be disabled by removing the laser arming panel from the aircraft. R00015LA Page 5 of 5 GENERAL NOTES NOTE 1. A current weight and balance report, including a list of equipment included in the certificated empty weight, and loading instructions when necessary, must be provided for each aircraft at the time of original airworthiness certification and at all times thereafter, except in the case of operators having an approved weight control system. NOTE 2. The following placard must be installed in clear view of the pilot: “THIS ROTORCRAFT APPROVED FOR DAY AND NIGHT VFR OPERATIONS” For additional placards, see the Rotorcraft Flight Manual. All placards required in the Rotorcraft Flight Manual must be installed in the appropriate locations. NOTE 3. Information essential to the proper maintenance of the helicopter, including retirement time of critical components, is contained in the Robinson R66 Maintenance Manual and Instructions f or Continued Airworthiness (RTR 660). Retirement times are listed in the “ AIRWORTHINESS LIMITATIONS” section. NOTE 4. Deleted as of March 10, 2015. NOTE 5. Any cockpit instruments installed by a 3 rd party must be marked with limit markings and range markings in accordance with Robinson’s marking scheme. NOTE 6. Deleted as of March 10, 2015. NOTE 7. Exemption No. 9589, dated January 28, 2008, has been removed since Robinson Helicopter Company was granted an Equivalent Level of Safety (ELOS) finding to CFR §27.695(a)(1), Number AT14992LA-R-S-1, dated February 20, 2013. The exemption allowed a powered flight control system without considering the jamming of a control valve as a possible single failure. There is no impact to R66 helicopters that have been delivered or are in service. NOTE 8. R66 helicopters equipped with the G132 Cargo Hook installation may be operated at up to 2900 pounds gross weight when the portion above 2700 pounds is jettisonable load on the cargo hook and the helicopter is operating at or below 7000 feet density altitude. See Cargo Hook Supplement to R66 Pilot’s Operating Handbook and FAA Approved Rotorcraft Flight Manual (RTR 661) for additional operating limitations. NOTE 9. Deleted as of December 20, 2022. NOTE 10.
