Re: Beechcraft King Air 250 Crashes Killing Businessman and His Family
I don't think so. It just didn't climb. Never had any yaw asymmetrical issues like out of center line thrust. I haven't read the accident report, but sure looks like a control lock was left in place and pilot could not pitch the nose up. Or, it was overloaded (that's a lot of people in there) and maybe a hot humid day with high density altitude. Never got out of ground effect, which is as high as the wingspan, maximum. This wont be a hard one to reconstruct the cause. |

Re: Beechcraft King Air 250 Crashes Killing Businessman and His Family
King Airs don't need flaps for takeoff. They do require a specific run-up procedure during the first flight of the day to adjust the throttle friction lock. Failure to do so can result in a throttle spring back on one engine which if unnoticed will cause a yaw and and crash. There's been a couple of documented incidents including one in the US in the last few years. |

Re: Beechcraft King Air 250 Crashes Killing Businessman and His Family
Excellent point. As stated by others: high humidity, high temperatures, short runway, overload, low take off RPM, prop pitch?....etc. Did not know about the throttle friction lock.
