Department of Transportation September 20, 2006 – Federal Register Recent Federal Regulation Documents

The FAA proposes to adopt a new airworthiness directive (AD) for all BAE Systems (Operations) Limited Model BAe 146 and Avro 146-RJ airplanes. This proposed AD would require determining the part number of the lift spoiler actuators/jacks (referred to after this as ``lift spoiler jacks''). For affected lift spoiler jacks, this proposed AD would require determining the date of manufacture of the lift spoiler jacks, repetitively inspecting the eye-end assembly of the lift spoiler jacks to detect discrepancies of the assembly or associated parts, and performing corrective actions if necessary. This proposed AD results from a report that a lift spoiler deployed in flight due to corrosion at the thread where the eye-end assembly was screwed into the piston of the lift spoiler jack. We are proposing this AD to prevent detachment of the eye-end assembly of a lift spoiler jack, which could result in uncommanded deployment of a lift spoiler in flight, and consequent reduced controllability of the airplane.

We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued by an airworthiness authority of another country to identify and correct an unsafe condition on an aviation product. We are issuing this AD to require actions to correct the unsafe condition on these products.

PHMSA is correcting a minor error in a final rule, published in the Federal Register on September 14, 2006. That final rule corrected editorial errors, made minor regulatory changes and, in response to requests for clarification, improved the clarity of certain provisions in the Hazardous Materials Regulations (HMR).
