Model OH-13H (Tomcat Mark 5A, 6B, 6C) helicopters that have a certain scissors assembly or weld assembly scissors bracket installed. The AD would require, within 60 days, determining and recording the total hours time-in-service (TIS) for each Parts Manufacturer Approval (PMA)-produced scissors assembly and weld assembly scissors bracket and would establish a life limit for each affected part. This proposal is prompted by the need to establish a life limit on scissors assemblies and weld assembly scissors brackets produced under PMA No. PQ808SW or installed per Supplemental Type Certificate (STC) No. SH2772SW. The actions specified by the proposed AD are intended to establish a life limit to prevent using a scissors assembly or weld assembly scissors bracket past its life limit, which could result in failure of the part and subsequent loss of control of the helicopter. 70 FR 38817 https://www.govinfo.gov/app/details/FR-2005-07-06/05-13237 05-13237 fr06jy05-23 RIN 2120-AA64 4910-13-P Docket No. FAA-2005-21725 Directorate Identifier 2004-SW-45-AD https://www.govinfo.gov/app/details/FR-2005-07-06/05-13237 https://www.govinfo.gov/content/pkg/FR-2005-07-06/html/05-13237.htm https://www.govinfo.gov/content/pkg/FR-2005-07-06/pdf/05-13237.pdf Air Transportation Aircraft Aviation Safety Safety 2 p. 38817 38818 70 FR 38817 Title 14 Part 39 14 CFR Part 39 RIN 2120-AA64 Airworthiness Directives; Bell Helicopter Textron Model 47D1, 47G, 47G-2, 47G-2A, 47G-2A-1, 47G-3, 47G-3B, 47G-3B-1, 47G-3B-2, 47G-3B-2A, 47G-4, 47G-4A, 47G-5, 47G-5A and Coastal Helicopters, Inc.
