GENERAL AVIATION ALENIA'S BUSINESS-AIRCRAFT SIMULATION Italian manufacturer Alenia has begun training with its first simulator, produced in collaboration with New York-based CAE-Link. Located in Naples, the VS-certificated three-degrees-of-freedom training device simulates operations in a twin-engined turboprop business aircraft. Cessna warns 400-series owners BY GRAHAM WARWICK IN ATLANTA Cessna has instructed owners of 400-series twins to in spect fuel-tank fuel-inlet float valves every 200h. Abnormal wear of a float valve is the suspected cause of the 19 June, 1992, crash of a Cessna 402C on a Grand Canyon sightseeing flight. The pilot and nine pas sengers died. The Adventure Airlines air craft crashed shortly after take off from Grand Canyon West Airport, Arizona, on the return flight to Las Vegas, Nevada. Vid eotapes recovered from the wreckage show that the right engine lost power during a right turn at low altitude, says the US National Transportation Safety Board (NTSB). The video evidence shows the pilot reaching between the front seats to where the fuel-selector handles are located, says the NTSB. Examination of all six fuel-inlet valves showed similar abnormal wear and one from the right wing could be made to stick in the open position. This may have allowed air to enter the right-engine fuel system, in terrupting the flow. Adventure's operational proce dures call for take-off from Grand Canyon West with the minimum allowable fuel in the wing tanks. The NTSB believes that "...frequent operations with partial fuel levels cause excessive repeated float movements and, in turn, cause abnormal wear". Examination of other Cessna 402Cs used for air-tour opera tions has revealed similar wear. The Board has called for "ur gent action" from the US Federal Aviation Administration and Cessna. It wants to revise the minimum fuel quantity for take off to preclude air entering a malfunctioning valve; to deter mine the rate of wear and estab lish an inspection programme; and to determine whether the present pass/fail pneumatic in spection can detect wear. Cessna says that reduction of the inspection interval from 600h to 200h is a quick re sponse and suggests that further action could follow examination of the inlet valves from the accident aircraft, which have now been handed over to the manufacturer and the FAA. • NEWS IN BRIEF TURKISH CITATIONS The Turkish State Airports Authority (DHMI) has pur chased two Cessna Citation Vs. The aircraft will be equipped with a microwave landing system (MLS) and semi-automatic flight-calibra tion equipment. Delivery of the two Cessnas is scheduled by the end of 1993. The DHMI is also planning to upgrade its two Beech King Air 200 calibration aircraft with new MLS equipment. A Flight International Conference LANDING AND APPROACH WHAT HAPPENS AFTER ILS? An international event for everyone who will be affected by the outcome of this vital debate With the full participation of IATA, ICAO and the FAA Geneva, 25 & 26 March 1993 This top-level Symposium is of vital importance to carriers, regulators and manufacturers. As the first international forum to debate the full range of precision approach options, it is an essential event for those with strong views on the type of system that will succeed Instrument Landing Systems (ILS). Key issues to be addressed include: Could ILS have a longer life-span than is gene rally anticipated? Have Global Navigation Satellite Systems (GNSS) come just in time to avoid the huge expense of buying Mic rowave Landing Systems (MLS)? Can civil aviation afford to take the risk of adopt ing a system that could be switched off - or downgraded - by the military at any time? How are the alternative systems being evalu ated? i Who will have the greater say in the final choice of system - the airlines or the regulators? • What will it cost - and how will it be paid for? How will a final decision be made? EMINENT SPEAKERS Such is the importance of this Symposium that we have attracted speakers of the very highest calibre. Amongst those making pre sentations - and sharing case studies - are ICAO, IATA, the FAA, United Air lines, British Airways, Lufthansa, Honeywell and Wilcox. This is the most controversial operational issue in air transport today, and all the major players - the people whose opinions really matter, will be attend ing. Come to the Symposium and you will hear all sides of the argument - with plenty of time to express your own opinion, too. Send now for further details, plus the full Conference Programme.
