Stall

November 3, 2012 - 1:25am

The NTSB has blamed the April 2, 2011, flight-test crash of a Gulfstream G650 on an aerodynamic stall and an uncommanded rolling moment that the pilots were unable to control. However, the Board also notes that it was the manufacturer’s rush to complete its aggressive flight-test schedule for obtaining certification that set the stage for the stall and uncontrollable roll.

Mid-Continent’s standby attitude module

The new MD 302 standby attitude module (SAM) developed by Mid-Continent Instruments and Avionics offers avionics installers another option for standby instruments, especially in panels with little extra space. The MD302 is entirely self-contained and provides attitude, altitude, airspeed and slip information in a small package measuring just two inches by five inches and weighing 1.6 pounds.

CenTex Aerospace received FAA STC approval for its Halo 250 conversion for King Air 200s today. The conversion raises the mtow for 200-series King Airs from 12,500 to 13,420 pounds and moves the turboprop twin into the commuter category. Included in the Halo 250 conversion are new safety systems that provide improved stall warning in icing conditions, aural over-speed warning, elevator out-of-trim warning, engine fire extinguisher capability, emergency cabin lighting and illuminated escape path floor markings.

The International Committee for Aviation Training in Extended Envelopes (Icatee) published an article this summer in the ICAO Training Report that said, “The number-one cause of commercial jet transport fatalities…[is] loss-of-control-in-flight (LOC-I).” Icatee chairman Sunjoo Advani said, “[The problem] cannot be simply solved through technology or through current pilot training paradigms.” Coincidentally, Boeing’s statistical summary of commercial jet airplane accidents worldwide operations 1959–2011 showed more fatalities caused by LOC-I accidents than by any other.

In findings released yesterday, the NTSB blamed the April 2, 2011, flight-test crash of a Gulfstream G650 on what it characterized as the aircraft manufacturer’s rush to complete its aggressive flight-test schedule.

The FAA released AC 120-109 on August 6 to address its concern about loss of control. The agency said some pilots are reacting incorrectly to aircraft stall indications, as in the case of the 2009 crash of Continental Express 3407 in Buffalo, N.Y. The agency also has concerns about pilots’ failing to recognize the insidious onset of an approach-to-stall during routine operations in both manual and automatic flight.

Diamond D-Jet Aerodynamic Design Frozen

Diamond Aircraft brought D-Jet prototype S/N 003 to EAA AirVenture Oshkosh last week, displaying publicly for the first time the jet’s new upswept wingtips. “At this point the aerodynamic configuration is frozen,” said Diamond president and CEO Peter Maurer. The new wingtips have “a positive effect on the stall speed and roll control, but also the overall aesthetics,” he added.

The final report on the crash of Air France Flight 447 is giving ergonomics specialists food for thought. One area of particular focus has been the stall warning, which the report says the crew ignored.

The National Transportation Safety Board issued four safety recommendations after its investigation into the January 27, 2009 loss-of-control crash of an Empire Airlines ATR 42-320 at Lubbock Airport (LBB), Texas. The NTSB said the flight crew failed to monitor and maintain a safe airspeed during an approach in icing conditions.
