March 2008 Aircraft Accidents and Incidents - Part I

Hi Readers: There was a total of 64 accidents/Incidents for March 2008 as reported by NTSB (National Transportation Safety Board). As of 4-16-08 the 19th and 23rd were unreported. There were 5 incidents, 15 fatal accidents with 35 fatalities, and 43 nonfatal accidents. There were 3 non-U.S. accidents, one public-use accident, 4 Part 137 accidents, 4 Part 135 accidents, 3 Part 121 accidents, and 49 accidents classified as GA accidents.


There were 7 helicopter accidents reported, the most serious accident (10 fatal) occurring 10 miles west of Santa Cruz, Peru when a Bell 412 EP, piloted by a U.S. certified air transport pilot and a peruvian provisional copilot, impacted mountainous terrain. There were two other Bell 206B accidents, one (2 minor injuries) in Alaska colliding with terrain - an aerial photography flight involving a loss of control while covering a dogsled race; the other, an agriculture flight, the skids contacting a field while spraying. There were 2 Robinson R22 helicopter accidents, one fatal - a combination photo and student training lesson, when the helicopter was observed to shed parts at low altitude and impact the ground. The tail cone had separated from the fuselage at a "right angle" and the main rotor blades exhibited "coning". Also, one of the main rotor blade sections exhibited an impression consistent in shape to the leading edge of the vertical stabilizer. Examination of the instrument panel revealed that the engine rpm needle was in a high limit position and the rotor rpm needle was in a low limit position. The pilot was properly rated for the flight. The other Robinson helicopter impacted terrain following a loss of engine power at 300 feet during a practice 180-degree autorotation at the Las Vegas, NM. airport following a flight from Broomfield, CO. There were no injuries. On March 9th a Sikorsky helicopter impacted a coal mound during a forced landing near Belmont, WV. The certified commercial pilot was seriously injured. The purpose of the flight was to remove construction equipment from a 620-ft tall powerplant smokestack. After 5 loads were removed successfully, the pilot refueled the helicopter and returned to pick up the sixth and final load. After lifting clear of the stack, the pilot noted that the calibrated load meter read 5,200# - an overload condition. Seconds later the pilot felt a high frequency vibration, which was followed by a yaw to the right and separation of the tail rotor assembly. After two 360-degree rotations, the pilot released the load, reduced the collective pitch and performed an autorotation. The helicopter sustained substantial damage during the hard landing. The 7th helicopter accident involved a Willey Rotorway Exec 90 flight to practice autorotation and simulated SE failures. After 45 minutes of flight both the Instructor and the Student noted that the engine tachometer read lower than the rotor tachometer. Assuming a following engine failure, an autorotation was made. The helicopter landed in soft terrain and rolled on its side.


There were 5 incidents - none sustaining injury. One, a Southwest Airlines B-737, Flight 411, collided, during taxi, with Southwest's B-737, Flight 15, during ground operations at Love Field, Dallas, TX. Both airplanes were damaged. While taxiing past flight 15 (stationary), the left winglet of Flight 411 contacted the left wing stabilizer of Flight 15. A Continental Airlines B-737 sustained minor damage when all four landing gear tires blew on touchdown at Houston, TX. Sounds like a very hard landing. A B-747 wet-leased to Saudia Arabian Airlines by Air Atlantic Icelandic experienced a fire in the the No. 3 engine pylon during the landing rollout at Dhaka, Bangladesh. On March 14th a UK Cessna 550 Citation experienced control problems in flight and landed at Edinburgh, Scotland for investigation - the flight originating in Spain. On March 26th a Great Lakes Aviation Raytheon 1900 D, operating as Flight 5187, en route to Farmington, NM., experienced an open cargo door after takeoff from Page, AZ.


There were 3 Alaskian accidents; one, a Cessna 185 ski-equipped airplane, which aborted the takeoff because the snow would not release from the skis. The airplane slid off the end of the runway and down an embankment at Takoti, Alaska. Another, a Bell 206B collided with terrain following loss of control whil maneuvering 59 miles SE of Nikolia, Alaska on a phot4o flight. The third accident occurred when a Stinson 108 rolled to the left on takeoff, struck the runway and nosed over. An inspection revealed that the ailerron control cables were misrouted, the direction of movement indicated in reverse.


The 4 Part 137 accidents involved agriculture operations and were minor, and a matter of pilot judgment.


The fatal accidents, as well as the nonfatal accidents, involved X-C flights, day and night, weather, an inflight breakup, and using the wrong fuel. All of these accidents will be covered in detail in Part II.

September 2007 Aircraft Accidents/Incidents

Hi Readers: Its time to review the September Accident/Incidents as reported by NTSB. There were 98 accidents and 2 incidents (7 non-U.S. accidents) of which 36 were fatal accidents accounting for 134 fatalities.
One incident was a Part 121 Air Carrier DC-9 engine fire warning in flight, and the other was a night VFR incident in which the Tower Controller instructed a Part 135 Lear Jet pilot to taxi into position and hold on R19R at Potomac airport in Washington D.C. Runway 19R was actually closed and the runway lights were off. The runway closure was advertised on ATIS and the closure was placed on the ground radar display in the Tower. The Tower Controller then cleared the pilot for takeoff. The FAA classified the incident as an operational error.
The September accidents, particularly the fatal accidents, show a conglomeration of accident types and indicated probable causes. There were 8 takeoff accidents (3 engine failures, 5 stalls or failure to clear trees and terrain); 9 loss of control and/or maneuvering at low altitude, including spin-ins; a collision of 2 airplanes, and a loss of control of one airplane, during the Reno, Nevada Air Races; one inflight collision with mountains; one flying into a thunderstorm and a crash shedding airplane parts; one formation-demonstration crash; 3 unknowns; one helicopter tail boom and rotor failure inflight; one where the passenger walked into the main rotor; and the accident involving Steve Fossett (never found). There was one GPS approach accident - a second attempt in a 100 ft overcast, with 1/4 mile visibility, and a zero temperature-dewpoint spread, resulting in 3 fatalities.
One fatality, and one serious injury, U.S. Customs accident, practising touch-an-go maneuvers, attempting a full-flap, short field landing, involved dropping the airplane in to the runway (10-12 ft.) and a bounce airborne, then a drift to the right of the runway centerline. The pilot applied power, resulting in a 30 to 40 ft pitchup and stall, further resulting in impact with terrain in a nose-low attitude and following fire. ( A typical example of how not to land an airplane)
One accident indicated an overload of the airplane on takeoff, resulting in 5 fatalities.
In general, we must conclude that the sum total of the accidents reflect carelessness, failure to follow the rules, poor decisions, and poor judgment. These accidents show deviation from safety of flight, and the type of accidents we would like to prevent. Also, unfortuneately, the type of accidents most likely to result in fatalities.
The poor judgment accidents continue for lack of knowledge and training. The poor planning and poor decision accidents we can correct, particularly those accidents involving X-C flight and weather. The carelessness and recklessness - Pilots must follow the rules.
We can attack the safety aspects of flying by separations, such as: 1. Local and X-C flight; 2. Pilot experience - flight hours, certificates, and proficiency issues; 3. Pilot - aircraft type certification; 4. VFR - IFR flying; 5.Rules and Regulations; 6. Aeronautical knowledge.
Supposedly we are doing this now - so what are we doing wrong?
Thanks for listening. R.S.
