THE WEEKLY ACCIDENT UPDATE IS AN INDEPENDENT PRODUCT OF MASTERY FLIGHT TRAINING, INC. NEW FAA REPORTS THIS WEEK 12/4 1940Z (1340 local): A Be50 s gear collapsed on landing at Osceola, Arkansas. Two aboard the Twin Bonanza were not hurt, and damage is minor. Weather: 15,000 scattered, visibility 10 miles with a three-knot surface wind. N633F (CH-70) is a 1954 B50 recently (October 2009) registered to an individual in Marion, Arkansas. ( Gear collapse on landing ; Recent registration ) 12/6 2015Z (1415 local): A Be35 s landed hard and its landing gear collapsed on touchdown at Dodge City, Kansas. The Bonanza then went off the side of the runway, incurring substantial damage. Two aboard the pleasure flight report no injuries. Weather was IMC: 500 overcast, visibility two miles in freezing rain and drizzle, with winds from 010 at 16 knots. N108L (D-8300) is/was a 1966 V35 registered since 1988 to an individual in Independence, Oregon. ( Hard landing airframe ice [more momentarily]; Substantial damage ; IMC ; Wind given the freezing rain, one possibility is the hard landing related to landing with a load of airframe ice. Circumstantial evidence appears to confirm this. A log of the flight shows the Bonanza departed from Blaine, MN at 10:52 local time on an IFR flight plan for Dalhart, TX. After passing through an area of precipitation radar returns the flight was diverted to Dodge City, where the mishap occurred. Local news reports the pilot decided to land at the Dodge City Airport because of the snow. During approach, however, the plane's air speed indicator stopped working, and [the airplane] hit the runway hard, snapping off his landing gear.) 12/9 0001Z (1601 local 12/8/09): A Be35 landed gear up at Corvallis, Oregon. The solo pilot was not hurt; damage is unknown and weather not reported. N8577A (D-1999) is a 1948 A35 registered since 2005 to a corporation in Sandy, Oregon. ( Gear up landing ) UPDATES FROM NTSB Events previously appearing in the Weekly Accident Update: **There are no new Beech piston aircraft NTSB reports this week.**

2 SUMMARY: Reported Hawker Beechcraft piston mishaps, year-to-date 2009: Total reported: 166 reports Operation in VMC: 115 reports Operation in IMC: 5 reports Weather unknown or not reported : 46 reports Operation at night: 13 reports Surface wind > 15 knots: 18 reports Fatal accidents: 19 reports Serious injury accidents (not involving fatalities): 6 reports Substantial damage: 64 reports Aircraft destroyed : 17 reports Recent registration (within previous 12 months): 24 reports (Note: FAA preliminary reports no longer identify the purpose of the flight involved in mishap. Consequently the number and percentage of Beech mishaps that occur during dual instruction will become less and less accurate over time. Since the late 1990s the percentage of Beech mishaps that take place during dual flight instruction has remained very consistently about 10%).
