In accordance with the National Environmental Policy Act of 1969, as amended (NEPA; 42 U.S.C. 4321, et seq.), Council on Environmental Quality NEPA implementing regulations (40 CFR Parts 1500- 1508), and FAA Order 1050.1E, Change 1, the FAA is announcing the availability of the Final EA for Issuing an Experimental Permit to SpaceX for Operation of the DragonFly Vehicle at the McGregor Test Site, McGregor, Texas, and FONSI.
Airworthiness Directives; Meggitt (Troy), Inc. Combustion Heaters
We propose to supersede Airworthiness Directive (AD) 81-09-09, which applies to certain Meggitt (Troy), Inc. (previously known as Stewart Warner South Wind Corporation and as Stewart Warner South Wind Division) Model Series 8240 (Models 8240-A, 8240-C, 8240E, and 8248), 8253 (Models 8253-A, 8253-B, and 8253-C), 8259 (Models 8259-A, 8259-C, 8259-DL, 8259HL2, 8259HR2, 8259JR2, 8259L, and 8259M), and 8472 (Models 8472C and 8472D) combustion heaters. AD 81-09-09 currently requires repetitive inspections of the combustion heater; repetitive general inspections of the combustion heater installation; and, for combustion heaters having 1,000 hours or more time-in-service (TIS), overhaul of the combustion heater. Since we issued AD 81-09-09, there was an airplane accident, and we received reports of the heater malfunction. This proposed AD would retain most actions from AD 81-09-09, add a calendar time to the repetitive inspections, and add more detailed actions for the general inspection. We are proposing this AD to correct the unsafe condition on these products.
