Description of the Type Design Change: Installation of a Supplemental Lighting System; installed in accordance with photos contained on DVD N587MG, dated August 14, 2008, and maintained in accordance with Instructions for Continued Airworthiness ICA 22247566E, dated September 5, 2008, or later FAA-approved revisions.

Limitations and Conditions: This rotorcraft employs Night Vision Imaging System lighting, commonly named NVIS, that has been certified to ensure the aircraft is compatible with Night Vision Goggles (NVG).

Compatibility of this design with subsequent modifications must be determined by the installer. The determination of compatibility with modifications that emit or reflect light must include an engineering compatibility evaluation approved by an aircraft certification authority. A copy of this certificate and the FAA-approved Rotorcraft Flight Manual Supplement (RFMS), FMS-22247566-6, approved September 5, 2008, must be maintained as part of the permanent records for the modified aircraft.

If the holder agrees to permit another person to use this certificate to alter the product, the holder shall give the other person written evidence of that permission.
