(previously known as Stewart Warner South Wind Corporation and as Stewart Warner South Wind Division) Model Series (to include all the variants) 921, 930, 937, 940, 944, 945, 977, 978, 979, 8240, 8253, 8259, and 8472 combustion heaters that proposed to supersede airworthiness directive (AD) 81-09-09. The NPRM proposed to retain most actions from AD 81-09-09, add a calendar time to the repetitive inspections, add more detailed actions to the inspections, and add a pressure decay test. The NPRM was prompted by an airplane accident and reports we received of the heater malfunctioning. This action revises the NPRM by adding combustion heater models series to the applicability and modifying the compliance times. We are proposing this SNPRM to correct the unsafe condition on these products. Since these actions impose an additional burden over that proposed in the NPRM, we are reopening the comment period to allow the public the chance to comment on these proposed changes. 81 FR 76532 https://www.govinfo.gov/app/details/FR-2016-11-03/2016-26428 2016-26428 fr03no16-12 RIN 2120-AA64 4910-13-P Docket No. FAA-2014-0603 Directorate Identifier 2013-CE-026-AD https://www.govinfo.gov/app/details/FR-2016-11-03/2016-26428 https://www.govinfo.gov/content/pkg/FR-2016-11-03/html/2016-26428.htm https://www.govinfo.gov/content/pkg/FR-2016-11-03/pdf/2016-26428.pdf Air Transportation Aircraft Aviation Safety Incorporation by Reference Safety 9 p. 76532 76540 81 FR 76532 Title 14 Part 39 14 CFR Part 39 RIN 2120-AA64 Airworthiness Directives; Meggitt (Troy), Inc.
