Federal Aviation Administration December 22, 2006 – Federal Register Recent Federal Regulation Documents

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: ``incidences have been reported to Britten-Norman Aircraft Ltd where cracks have been found in the inner shell of the pitot/static pressure heads. This could result in incorrect readings on the pressure instrumentation, e.g. altimeters, vertical speed indicators (rate-of-climb) and airspeed indicators.'' The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.

This notice proposes to amend Part 71 of the Federal Aviation Regulations (14 CFR Part 71) by establishing a Class E airspace area extending upward from 700 feet above the surface at Potosi, Washington County Airport, MO.
