A personal narrative is presented in which the editor shares experience of the U.S. airplane accident due to collapsed landing gear, right wing, damaged engine and adds that were no immediate reports of injuries after the accident.

Several letters to the editor are presented in response to articles in previous issues including "Peer Forward," in the August 23, 2010 issue, "Glass cockpit Pitfalls," by Karl Sutterfield in the August 16, 2010 issue, and "Wheel Wear Revisited," in the August 16, 2010 issue.

Several letters to the editor are presented in response to articles in previous issues including "Smoke and Mirrors" published in the July 26, 2010 issue, "Another Spin on Wheels" by David Rada in the July 5, 2010 issue, and the editorial "Safeguard Transatlantic Relations" in the July 26, 2010 issue.

Reports the contract agreement between Japan Aircraft Manufacturing Co. with Boeing Co. to supply landing-gear housing doors for the 747-400 jets in the United States.

The article focuses on faults in actuators of airplanes in the U.S. The left main gear downlock actuator stopped working while the Cessna 201L Centurion airplane was in the sky and the landing gear was found in the up position. Inspection revealed that the flap actuator of Cessna 152 aircraft had defective input shaft and failed coupler to the electric motor.

The article presents information on the phenomenon of hydroplaning. Based on a definition given by the U.S. Federal Aviation Administration (FAA), hydroplaning refers to a condition that can exist when an airplane is landed on a runway surface contaminated with standing water, slush and/or wet snow. It describes the three basic types of such a phenomenon, one of which is dynamic hydroplaning. Also noted is the significance of a proper braking technique, if hydroplaning should occur.

The article reports on the move of CW Aerotech Services of seeking a supplemental type certification (STC) for the installation of its hydrogen-hybrid landing gear on AS366G Dauphin helicopters and Eurocopter AS365N in the U.S. Bob Wehr, executive vice president of CW Aerotech, notes that the landing gear has already acquired the Form 8110 clearance of the U.S. Federal Aviation Administration (FAA). Wehr notes the benefits of the modified landing gear such as the simplicity of installation.

The article reports on the findings of the U.S. National Transportation Safety Board (NTSB) about US Airways Inc.'s Express Bombardier Dash 8-300 that was forced to land at Philadelphia International airport with its nose landing gear retracted. In a preliminary report on the incident, the NTSB says that the though the crew had heard the noise before, pilot and first officer of Flight 4551 continued with the flight to Philadelphia as they felt this was a normal noise.

The article focuses on the partnership formed by Delta Air Lines and Gibraltar-based Chorus Motors to develop the first production electric wheel drive for commercial aircraft ground maneuvering. The agreement calls for the U.S. carrier to invest in Chorus Motors company WheelTug to develop a wheel-drive system for the Boeing 737 Next Generation models. The partnership is expected to be approved by 2009, according to Chorus.

The article focuses on some of the proposed rules for helicopters and airplanes in the U.S. For the Bell 204, 205, 210, 212 and 412 helicopters, certain checks and inspections of each tail-rotor blade at specified intervals, and repair or replace, as applicable, any unairworthy tail-rotor blade should be conducted. Inspect the nose landing gear and the nose gear door to determine the part number and serial number of the selector valves of Bombardier Challenger 600, 601 and 604 airplanes.

The article presents information related to various developments in science and technology. Orders are placed by Air France to install the Boeing Class 3 Electronic Flight Bag for its entire fleet of 777 airplanes. Goodrich Corp. has been selected by Boeing Co., to provide landing gear maintenance for the U.S. Air Force's fleet of C-17 aircraft.

The article reports on the new alloys and prototypes developed and technology used by Questek Innovations LLC in the U.S. The company has used its proprietary computer simulation technology for designing their alloys. These materials produced were used to make off-road vehicles faster, enhance the strength of and environmental safety, landing gears of airplanes, and boost performance of sporting goods. One of its most recent developments is airplane landing gears for military application.

ARM Aerospace has come up with a way to increase the storage capacity of hangars. The Aero-Lift makes it possible to store two airplanes in almost any hangar by lifting one aircraft into the air and using the empty space underneath to store an additional aircraft. It is a cantilevered, single-post lift design that uses a jackscrew mechanism and electric motor, rather than a traditional hydraulic system. Aircraft are hoisted on a large girder that branches off to three docks that can be adjusted quickly to accommodate the landing gear configuration. ARM says engineering analysis has shown the units are suitable for use in earthquake risk areas, including California and Alaska.
