A proposed AD would mandate replacing the pitot probes on nearly 160 U.S.-registered Hawker 800XPs because of reports that they have frozen above FL290, causing erroneous airspeed indications. New probes and their installation would cost about $14,500 per airplane, according to the FAA. Replacement would be required at the next 24-month inspection after the compliance date of the directive. Comments on the proposal are due by November 28.

“Welcome to Lear Jet Country,” a marketing slogan that attached itself to the early-20-series Lear Jet, is likely to be remembered only by industry old-timers who recall the airplane’s ability to take off and climb to 41,000 feet without effort. It is a capability that disappeared with the advent of the Learjet 35/36.
Operators of U.S.-registered CitationJets must disengage the pitch-trim/ autopilot circuit breakers to prevent runaway pitch trim, a condition that has led to at least one accident, according to an October 21 AD (2203-21-17). A CitationJet was ditched on July 22 in Penn Cove in Coupeville, Wash., following a loss of elevator trim control, resulting in an uncommanded nose-down pitch attitude.
As part of a major consolidation project that it says will save $25 million a year, Bombardier has embarked on an 18-month project to consolidate all Learjet production, completions and deliveries in Wichita, and all such Challenger work in Montreal.
The first test flights of a Cessna Citation X equipped with Winglet Technology’s new elliptical winglets are proceeding well, according to Bob Kiser, president of the Wichita-based modification kit manufacturer. The winglets are expected to give the airplane an even higher maximum cruise speed at high altitude as well as improved climb performance and longer range.
In a bid to expand its capabilities to service larger turbine engines, Standard Aero announced the purchase of TSS Aviation in Cincinnati for $65 million. Standard Aero and Landmark aviation were added to Dubai Aerospace Enterprise’s (DAE) rapidly growing portfolio of aviation businesses in August as part of a $1.9 billion buyout from the Carlyle Group.
Gulfstream Aerospace acquired the maintenance operation of BBA Aviation’s facility at London Luton Airport, making the facility the first Gulfstream-owned service center outside the U.S. The facility will continue to provide maintenance for Citations, Falcons and Hawkers, as well as all Gulfstreams.
Buyers of new Gulfstream 200s now will receive a five-year or 2,500-hour maintenance and training program, similar to what Gulfstream has been offering buyers of new G400s and G550s since last September. Under the extended plan, all covered maintenance, inspections and parts are provided by a Gulfstream or General Dynamics service center, and includes the cost of labor.
UK-based Avionics Mobile expects to complete by the end of the month an RVSM equipment and operational package for the BAC 1-11. In addition to verifying the RVSM capability of the aircraft’s original Elliott autopilot, the package includes air-data displays from IS&S and flight-test evaluations from Aeromech. Meanwhile, Thunder Avionics, a division of the Thunder Aviation FBO at Spirit of St.
Duncan Aviation of Lincoln, Neb., has received RVSM group certification for the Westwind 1124 and RVSM equipment certification for the Astra series. Basic equipment installation for the Westwind (including air-data computers and IS&S altimeters) costs $160,400, depending on aircraft configuration. A pneumatic standby altimeter is an additional $12,000 (installed).
