Fabrication of the Onboard Model 200-095-00 Multi Channel Electrical Slip-Ring Kit in accordance with Onboard Systems Master Drawing List No.

155-022-00, Revision B, dated March 11, 2010, or later FAA approved revision; and installation of this system in accordance with FAA approved Onboard Systems Owner’s Manual No. 120-034-01, Revision 11, dated March 11, 2010, or later FAA approved revision. Inspect the Multi-Channel Slip-Ring Kit in accordance with Section 4 of Onboard Systems Owner’s Manual No. 120-034-01, Revision 11, dated March 11, 2010, or later FAA approved revision.

Approval of this change in type design applies to only those Bell model rotorcraft listed on AML SH5758NM, amended May 17, 1999, or later FAA approved amendments, which are equipped with an FAA approved installation of Bell cargo hook suspension assembly, P/N 204-072-915-25 or P/N 204-072-915-103, with either Breeze-Eastern Cargo Hook P/N SP7109-12 or SP7109 62. This approval should not be extended to rotorcraft of these models on which other previously approved modifications are incorporated unless it is determined by the installer that the relationship between this change and any of those other previously approved modifications, including changes in type design, will introduce no adverse effect upon the airworthiness of that rotorcraft.

End SH5758NM Limitations and Conditions continued:

Rotorcraft modified in accordance with this STC must be operated in accordance with an FAA approved copy of the Rotorcraft Flight Manual Supplement, revised May 17, 1999, or later FAA approved revision. A copy of the Certificate, Continuation Sheet No. SH5758NM, AML No. SH5758NM, and FAA approved Rotorcraft Flight Manual Supplement must be maintained as part of the permanent records of the modified rotorcraft.

WARNING

The Onboard Multi-Channel Slip-Ring Kit 200-095-00 is offered as a means of passing electrical current across the rotation junction between the rotorcraft cargo hook suspension system and suspended load. This kit must be considered as a electrical part, only, and not as a completed electrical system. Onboard has not evaluated any end-to-end use of this part other than the cargo hook electrical release mechanism defined herein and no other use is assumed or implied.

Accordingly, it is the responsibility of the installer and their Authorized Inspector (AI) to verify that each electrical system incorporating this Slip-Ring kit meets the applicable electrical requirements of the Federal Aviation Regulations. All electrical considerations such as electrical load determinations, voltage drops, electrical interference, electrical buss and circuit protection, etc. are the responsibility of the end user and may require further FAA approval.

Onboard has accomplished satisfactory electrical load testing of the elements of this Slip-Ring kit, only, and has demonstrated maximum load ratings of 10 amps (continuous) and 30 amps (intermittent for 30 seconds) for the standard 28 VDC electrical system. Electrical loading above these currents or time limits may harm kit performance. The cargo hook mechanical and electrical release systems for the Bell model 204-072-915-25 and 204-072-915-103 suspension systems have been evaluated and found to be acceptable with this kit installed.

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 the permission.
