The Hawker service center in Chester, England will become a separate business and remain at the Chester site after Hawker production is moved to Wichita in 1997, said Raytheon officials at Paris. Also announced at the Air Show were plans for a new service facility on the East Coast, the opening of a European sales office in Frankfurt, Germany, and an order from Executive Jet Aviation for three more Hawker 1000s for EJA's NetJets shared-ownership program.

You'd think that all the bugs would be worked out by the time an aircraft reaches its golden anniversary-particularly when 12,731 units have been manufactured. Apparently not. The FAA recently published a proposed AD for Boeing B-17E, F and G models that would require removal of the wings to inspect the tubular spar chords of the inner wing for cracking and corrosion. The agency said that the inner wing-spar assembly is susceptible to moisture accumulation that can result in corrosion and cracking.

Beech donated two Starship airframes (minus engines and avionics) to NASA for studies relating to the Advanced General Aviation Transport Experiments (AGATE) program (B/CA, October 1994, page 38). The airframes, originally Starship prototypes, will first be used as a test bed for AGATE-developed technologies. Ultimately, the airframes will be destroyed in crash tests to evaluate the crashworthiness of composite structures and new occupant-protection systems. Earlier, the LearFan met the same fate in tests (B/CA, March 1993, page 30).

ICAO and the FAA have scheduled a seminar August 28-29 in Washington, D.C. to discuss changes in operational requirements that will occur due to implementation of 1,000-foot vertical separation minimums between FL 290 and FL 410 in the North Atlantic Track Region. Those minimums are scheduled to be in effect by January 1, 1997 (B/CA, June, page 43). For details of the seminar program, contact the FAA's Carl Bowlin in Washington, D.C. Phone: (202) 233-5172.

U.S. Customs is planning to allow ``pre-registered'' operators reentering the United States from Canada to clear customs via telephone and, thereafter, to land at any U.S. public-use airport. Under the program, scheduled to start this summer, customs agents would meet selected flights for random inspections. Customs also is setting up a 24-hour 800-number for pilots to use to arrange clearance releases up to 72 hours prior to returning to the United States.

The concept of CRM training originated in NASA human factors studies, concluding, among other things, that ``captains have failed, sometimes at critical points in the flight, to take advantage of important resources that are available to them. . . .'' Thus, it is important to know and manage the resources that contribute to flight safety.

The FAA has awarded more than 114 STCs to Sabreliner and Midcoast since late 1977. The following sampling gives a good idea of the companies' diverse capabilities in avionics, systems and cabin-interior modifications and retrofits.

Effective July 20, several subareas of the Class B Airspace for North Carolina's Charlotte/Douglas International Airport will be reconfigured, but the 10,000-foot upper limit will remain. The changes generally reduce the amount of Class B Airspace, but during the proposed rulemaking stage, the FAA rejected several requests from general aviation representatives and advocates that the ceiling be lowered to 8,000 feet (B/CA, May 1994, page 20).

Computing Technologies for Aviation has introduced FOS/2, an OS/2 version of its software geared for flight departments. The Scheduler's Tool Kit ($995 for single license, $1,495 for network) is designed to ease scheduling and dispatching chores. It provides a time and distance calculator for computing local arrival or departure time, fuel burn, time en route, time-zone change and cost. Included are 175,000 locations in the United States and U.S. territories, and U.S. airport data.

B/CA looked at three dedicated, retrofittable trend-monitoring systems: two available now for turboprop- and turboshaft-powered aircraft and a third which will be available for business jets in about a year. Descriptions of these systems follow. (In addition to these stand-alone units, Honeywell's Primus and Collins' Pro Line 4 integrated avionics systems also provide varying levels of trend monitoring and condition monitoring-from simple engine-watching to keeping an electronic finger on nearly every system in the airframe.)

Loss of engine power on a test flight in Israel forced the prototype of the Israviation ST50 all-composite, single-engine turboprop to make an emergency landing. An Israviation spokesman said that apart from the propeller, damage was ``minor.'' Cause of the problem with the P&WC PT6A was not known at press time, but a new engine has been installed and repairs finished. The prototype was developed by Cirrus Design of Duluth, Minnesota (B/CA, May, page 65).

A large number of business aircraft pilots are having to train and work-with mixed emotions-alongside a new member of the cockpit resource team-the FMS. FMSes are being installed in many aircraft because of the growing sophistication of aircraft, ATC systems' complexity and the accompanying increase in workload that would otherwise warrant the assignment of another crew-member. Instead of adding a third per- son, assigned to navigator and flight-engineer duties, aircraft designers add an FMS to the avionics package.

Learjet is quite candid in responding to operators' complaints about the prior lack of a Learjet 60 simulator. ``There's no good answer [for why it was delayed],'' company President and CEO Brian Barents admitted. The Learjet 60 simulator, now installed in FlightSafety International's Tucson facility, was slated for FAA Level D approval by the end of June.

Italy's Agusta Group introduced a single-engine helicopter at the Paris Air Show in June. The prototype of the eight-seat, skid-gear A119 Koala is powered by Turbomeca, but Agusta is considering offering the Allison 250-C40. Certification of the A119 is scheduled for late this year. Agusta also unveiled another version of its twin-turbine A109 series. The new A109 (dubbed ``Power'') is equipped with two 639-shp PW206C turbines, putting the aircraft midway between the A109C with 450-shp Allisons and the A109K2 with 771-shp Allisons.

The former Mather Air Force Base, 12 miles from downtown Sacramento, is now Sacramento Mather Airport, and Trajen Flight Support is the former military airfield's first and only FBO. Trajen now offers full line service and hangar parking. There are no noise restrictions or airline traffic. The airport, with an 11,300-foot runway and IFR approaches, also is home for an 18-hole golf course. In the near future, Trajen plans to introduce maintenance.

Photograph: Soloy's Cessna 208B Dual Pac structural test and design mockup. Over 1,500 members, vendors and supporters of the National Air Transportation Association weathered rain, hail, floods and high winds to attend the aircraft service organization's 55th annual convention and trade show in New Orleans in May. Attendance may have been down by as much as five percent from earlier estimates because of the severe weather.

The Automated Surface Observing System (ASOS) still is plagued by delays that are likely to put off commissioning more installations until year-end. About 320 of 537 systems have been installed, but only two-at Montrose, Colorado and Grand Canyon, Arizona-have been commissioned. Delays are attributed to problems with obtaining long-line communications, a National Weather Service moratorium imposed due to technical problems, and an FAA agreement with ATC controllers not to install ASOS at airports with control towers.

When the FAA adopted a new regulation governing aircraft seat construction and testing in 1988, few in the industry foresaw major problems with the rule.

In the unlikely event that all of the remaining 370 Sabreliner business jets were suddenly to disappear from the face of the Earth or its atmosphere, the aircraft's main source of support, Sabreliner Corporation, would not instantly go out of business.

The FAA has a problem. The demand for ATC services is growing faster than the agency is able to flex itself to adapt, leading to limited access and operating restrictions. Those restrictions, in turn, create inefficiencies that impose a cost on users in both time and money. The FAA's statistics tell the tale. Agency workload measures show a steady increase in traffic volume.

Association of Flight Attendants issued a study strongly supporting the use of child safety seats aboard commercial aircraft. Representative Jim Lightfoot (R-IA) is expected to use the study to help obtain passage of his bill (H.R. 1309) that would require the use of child-restraint systems for passengers under two years of age. To date, the FAA has opposed mandatory use of child safety seats until other studies' results can be considered (B/CA, December 1994, page 24).

The special flight restrictions for operating above the Grand Canyon will likely be extended for another two years. The restrictions were enacted four years ago and have previously been extended to allow time for the National Park Service to complete a study involving aircraft overflight impacts in the Canyon. Recommendations from the completed study were sent to the FAA, which said extending the restrictions gives it ample time to review the studies.

Enhanced Vision System and Synthetic Vision System are two terms that currently roll off the tongues of many technocrats in the aviation industry. These two terms often are used interchangeably, although, in a pure sense, they are quite different concepts.

Examples from the CVR and the captain's testimony provide information on specific performance and behavioral occurrences that fit the expected effects of fatigue on human functioning. The hypothesis that fatigue affected the crewmembers' performance is supported by the amount of cumulative sleep loss, continuous wakefulness and circadian disruptions (jet lag) experienced by the entire crew.
