AOPA Expo 2006: Focus On The Future

AOPA's annual Expo opens today in Palm Springs, Calif., with a sold-out exhibit hall and a jam-packed schedule of events. With the theme "AOPA looks to the future," the three-day show highlights technological advances and regulatory issues that will affect GA in the years ahead. FAA Administrator Marion Blakey will address attendees tomorrow, and other sessions will feature AOPA President Phil Boyer and top industry leaders. Expect lots of talk about user fees and what this week's election returns might have regarding this agenda. The exhibit hall is filled with displays from about 500 aircraft manufacturers, showing avionics, flight gear, navigation tools, flight-training services and more. Additionally, more than 60 hours of seminars are scheduled. AOPA will also be recruiting members to volunteer as mentors for flight students in the Project Pilot program.

New Airplanes On Display At Expo

Some 108 aircraft taxied down blocked-off streets yesterday morning during the "airplane parade" and are now on display outside the Palm Springs Convention Center. At the static display, visitors can expect a first look at the brand-new 1200-hp Epic Dynasty Jetprop, but don't look for the three Eclipse 500s that are supposed to be on display. Eclipse said it is upgrading the aircraft with performance modifications and couldn't get them to Expo as planned, meaning attendees will have to settle for a mockup on the convention floor. Diamond Aircraft says it is hosting its largest AOPA Expo display ever, and is promising a "special announcement" at a press conference later today. Columbia Aircraft is there, ready to hand over the keys to its 500th aircraft. In the LSA area, Cessna is showing its brand-new LSA prototype, which flew for the first time just last month. While visitors won't be allowed to climb inside the Cessna LSA, they can press up against the windows to get a good look at the two-seater. Also new at the LSA lineup is Nexaer's swoopy-looking prototype, which flew for the first time about two weeks ago. Experimental aircraft will also have a place at the show. The first Lancair ES-P, a four-place, fixed-gear, graphite composite pressurized homebuilt with hot wing de-icing, will be there. Watch for more AVweb reports live from the show, coming to your inbox tomorrow and Saturday.

Lawsuit Filed In Brazilian Midair back to top 
 

Suit Alleges Malfunction, Mistakes

Lawyers for the relatives of 10 victims of September's midair crash in Brazil filed suit this week in a U.S. court against ExcelAire, the owner of the Embraer Legacy jet that collided with a Boeing 737, and also named Honeywell, the manufacturer of the Legacy's transponder. "The pilots of the ExcelAire jet were flying at an incorrect altitude at the time of the collision and the ExcelAire jet's transponder ... was not functioning at the time of the collision," the lawsuit states. The suit alleges that the transponder stopped operating before the collision, which also disabled the Traffic Collision Avoidance System (TCAS), and that the Legacy jet was flying at the incorrect altitude. The suit also alleges that the pilots failed to take the steps they should have after they lost radio contact with controllers, and didn't correctly use the transponder and TCAS. Design flaws in the Honeywell avionics and inadequate training of the pilots contributed to the accident, the suit alleges.

Honeywell, ExcelAire Respond

Both companies were quick to respond. "Honeywell is not aware of any evidence that indicates that its transponder on the Embraer Legacy was not functioning as designed or that Honeywell was responsible for the accident," Honeywell spokesman Paul Loughran told AVweb on Tuesday. "The National Transportation Safety Board and the Brazilian authorities are still investigating the tragic crash and have not yet determined a probable cause." Honeywell's statement added that the company had not yet been served with the complaint filed in federal court in New York and could not comment on specific allegations in that lawsuit. ExcelAire also said the lawsuit is premature. The facts surrounding the accident have not yet been fully investigated and established in a comprehensive accident investigation, according to Robert Torricella, a Miami-based aviation attorney representing the ExcelAire pilots. "In the face of recent confirmations that air traffic control cleared and directed the ExcelAire Legacy to fly to Manaus at 37,000 feet, repeated suggestions that ExcelAire's pilots were flying at the wrong altitude are baseless," Torricella said in a statement e-mailed to AVweb yesterday. The ExcelAire pilots are still being detained in Brazil. Torricella said the pilots were following instructions from air traffic control. "According to international aviation regulations and norms, air traffic control directives take precedence over a written flight plan and those directives effectively amend the written flight plan," he said. "It is the flight plan cleared by air traffic control at the time of departure -- and not the prior written flight plan -- that governs the conduct of the flight. Here, the flight plan cleared by air traffic control at the time of departure required the Legacy to fly all the way to Manaus at 37,000 feet and, absent contrary directives from air traffic control, the Legacy was obligated to follow its cleared flight plan. As the findings of the investigation are made public, we are confident that ExcelAire's pilots will be exonerated." ExcelAire is based in Ronkonkoma, N.Y., and has pledged its full cooperation in the investigations currently underway in Brazil. "ExcelAire expresses its deepest sympathies to the families that lost loved ones in the tragic accident of September 29, 2006, in Brazil," the statement said.

Changes In Congress Will Affect GA, Says AOPA

On Tuesday, voters changed the balance of power in the U.S. House of Representatives, and apparently the Senate, from Republican to Democratic, and this will have a positive impact for pilots, says AOPA President Phil Boyer. "Now we can be assured of a fair hearing from people who understand aviation and aren't beholden to the White House," Boyer said. Aviation user fees have been strongly pushed by the Bush administration. But the power shift in the House will most likely put Rep. Jim Oberstar, D-Minn., in charge of the House Transportation and Infrastructure Committee, and he is a long-time friend to GA, AOPA said yesterday. Any law to change the way the FAA is funded will have to originate in Oberstar's committee, and he would control what legislation gets passed out to the full House for a vote. He has historically opposed corporatizing or privatizing air traffic control, and he is highly skeptical of any changes to the current, proven FAA funding system, AOPA says. "We're well positioned with the people newly in power who will, at the very least, listen to us," Boyer said.

"Silent Aircraft" Debuts Loudly

Plans for a quiet, energy-efficient airliner that could be flying in less than 25 years were unveiled Monday afternoon by researchers from Cambridge University and the Massachusetts Institute of Technology (MIT). The design uses technology that should be ready to fly by 2030. Besides reducing noise around airports, the airplane would require about 25 percent less fuel. It would use a flying-wing design, eliminate flaps and slats, simplify the landing gear, improve its aerodynamics and mount the engines above the fuselage to screen the noise from the ground. Variable-size jet nozzles would allow for slower jet propulsion during takeoff and climb for low noise, and would be optimized for maximum efficiency during cruise. The research that led to the design was sponsored by the Cambridge-MIT Institute and supported by Rolls-Royce and Boeing. Click here to watch a simulated flyby video. More details about the design are at the BBC Web site.

Two Bonanzas Land On Same Runway, At Same Time

On Monday afternoon, pilot Robert Johnson had just touched down in his Bonanza at the Los Alamos County Airport in New Mexico when his passenger noticed an ominous-looking shadow just ahead. Another Bonanza, on short final, was trying to land on the same runway, and crashed into the top of Johnson's airplane. Unhurt, Johnson struggled to maintain control as the two entangled aircraft rolled down the runway and coasted to a stop. The pilot of the second airplane, who also was uninjured, said he'd mistakenly been tuned to the wrong radio frequency, and the first Bonanza was not visible to him as he flew the approach. Johnson and his passenger were unable to open the doors or windows and had to be extricated from the cockpit by rescue workers. A similar accident occurred in Florida in December 1999. A Piper Cadet and a Cessna 152 collided on final and landed while stuck together. Nobody was hurt, and damage to both aircraft was minimal. The airplanes were separated and the Piper flew home the next day. Both the Piper pilot and the 152 pilot spoke with AVweb's Joe Godfrey to describe their experiences.

Lessons Learned In Past Midairs

The NTSB has determined that in two midair collisions involving GA aircraft, the failure of the pilots to see and avoid was the main cause of the accident. However, in both cases failures of air traffic control were cited as contributing causes. In 2002, three people died when a Mooney and a Beech Duchess collided while on downwind for Runway 24 at Palomar, in Carlsbad, Calif. In August 2005, a Cessna 150 and a de Havilland DHC-2 Beaver collided in Renton, Wash. A student and instructor in the 150 were killed. In the two cases, a controller either gave inadequate information or missed a chance to avert the crash, the NTSB said. In the California crash, both pilots were talking to the control tower. In the Washington accident, both aircraft were under the control of a developmental air traffic controller who was being supervised by a certified controller.

Question of the Week

This Week's Question | Last Week's Results

PREVIOUS RESULTS ***

Does the average pilot's sense of invincibility increase when flying an aircraft with an emergency parachute recovery system?

That's the question we put to AVweb readers last week, and your responses left little in doubt: AVweb readers do think parachutes foster a false sense of security. At least, 57% of you think so.

Another 24% said no, while the remaining 19% of those polled were unsure.

For the complete breakdown of last week's poll answers, click here.

THIS WEEK'S QUESTION ***

The November elections are behind us, and now AVweb wants to know if you think the power shift will affect the hot issue of user fees. Could the shift of control from the Republicans to the Democrats in the House of Representatives, and possibly the Senate, will thwart the push for aviation user fees in the next FAA reauthorization bill?

AVweb's "FBO of the Week" ribbon goes to Carolina Air Center at KHXD in Hilton Head, S.C.

AVweb reader Matt Thompson complimented the FBO staff for giving piston operators the same red carpet treatment as the jet set.

" I stopped here three times in nine days in two different aircraft (a Beech B36TC and a Cirrus SR22). The quality of service was superb. While many resort facilities really roll out the red carpet for the jet set, Carolina Air Center gave me the same service I have received when arriving in much larger corporate aircraft. It was a pleasure doing business with these folks. I would highly recommend them to anyone passing through the area. And I might add, they are the only FBO on the field. Many thanks for this excellent level of service."
