Federal Aviation Administration October 29 Dornier Luftfahrt GMBH Models 228-100, 228-101, 228-200, 228-201, 228- 202, and 228-212 Airplanes: AD, final rule, requires amending the Limitations Section of the Dornier 228 Pilot's Operating Handbook (POH) to prohibit the positioning of the power levers below the flight idle stop while the airplane is in flight. This POH amendment will include a statement of consequences if the limitation is not followed. This AD results from numerous incidents and five documented accidents involving airplanes equipped with turboprop engines where the propeller beta was improperly utilized during flight. The actions specified by this AD are intended to prevent loss of airplane control or engine overspeed with consequent loss of engine power caused by the power levers being positioned{{Page 56060}}below the flight idle stop while the airplane is in flight. Effective December 5. Docket No. 97- CE-23-AD; Amendment 39-10181; AD 97-22-09. Contact: J. Mike Kiesov, 816/426-6934; fax [phone]. Saab Model SAAB SF340A and SAAB 340B Series Airplanes: Proposed AD to require an inspection to determine the serviceability of the fire extinguisher of the forward lavatory waste bin, and corrective actions, if necessary. This proposal also would require installation of a placard adjacent to the fire extinguisher in the forward lavatory waste bin. This proposal is prompted by the issuance of mandatory continuing airworthiness information by a civil airworthiness authority. The actions specified by the proposed AD are intended to prevent leakage of the fire extinguishing agent, which could prevent proper distribution of the agent within the lavatory waste bin in the event of a fire. Comments due November 28. Docket No. 97-NM-135-AD. Contact: International Branch, 425/227-2110; fax [phone]. Dornier Model 328-100 Series Airplanes Equipped With Burns Aerospace Corporation Passenger Seats: AD, final rule, revises an existing airworthiness directive (AD), applicable to certain Dornier Model 328- 100 series airplanes, that currently requires modification of the restraining systems of certain passenger seats by replacing anchor point fasteners with fasteners that are able to withstand required 16g load conditions. That AD was prompted by a report indicating that the restraining systems on these seats failed to meet 16g test load requirements during dynamic testing. The actions specified by that AD are intended to prevent the fasteners from failing, which could result in release of the seat restraint and consequent injury to passengers. This amendment revises the applicability of the existing AD to specify serial numbers of the affected passenger seats. Effective November 13.
