We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as two fatigue failures of flap carriage rollpins occurred on in-service airplanes. The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.

This is to notify the public that we (PHMSA) have discovered the unauthorized marking of high-pressure compressed gas cylinders, mainly cylinders containing welding gases, fire extinguishers, and self-contained breathing apparatus, by Consulting and Safety Specialists, Inc. (CSSI), located at 924 Lefort Bypass, Thibodaux, LA 70301. On November 30, 2006, an inspector from PHMSA's Office of Hazardous Materials Enforcement (OHME) conducted a compliance inspection of CSSI. As a result of that inspection, PHMSA has determined that CSSI did not hold a valid Requalifier Identification Number issued by DOT while requalifying (inspecting, testing, or certifying) high-pressure compressed gas cylinders. In addition, CSSI marked and certified an undetermined number of DOT specification and/or special permit high- pressure compressed gas cylinders as being properly tested in accordance with the Hazardous Materials Regulations (HMR), when it had not verified its equipment to be accurate as required by the HMR. A hydrostatic requalification and visual inspection, conducted as prescribed in the HMR, are used to verify the structural integrity of a cylinder. If the hydrostatic requalification and visual inspection are not performed in accordance with the HMR, a cylinder with compromised structural integrity may have been returned to service when it should have been condemned. Extensive property damage, serious personal injury, or death may result from rupture of a cylinder. Cylinders that have not been requalified in accordance with the HMR may not be charged or filled with compressed gas or other hazardous material and offered for transportation in commerce.

The FAA is adopting a new airworthiness directive (AD) for certain Alpha Aviation Model R2160 airplanes. This AD requires you to inspect the fuel pressure indication system for leakage at the end of the adapter in the fuel pressure indication system. This AD results from the possibility of fuel leakage at the end of the adapter in the fuel pressure indication system. We are issuing this AD to detect, correct, and prevent fuel leaks in the fuel pressure indicating system. This failure could allow fuel to leak near the exhaust manifold and lead to a fire.
