C172S Landing accident
A solo student (not mine) had a landing accident today. Landed on the
nose wheel, porpoised a few times, and stalled the airplane in a slightly nose down attitude. The student was unharmed, but the aircraft is totaled. Our flight school has been moving towards an all-new aircraft fleet. It it wise to be putting solo students out in a $170,000 airplane? |

The student was unharmed, but the aircraft is totaled. *sigh* One time not long after DH learned to fly, we arrived at the airport to pick up our rented steed. Uh-oh. News vans all over. Rescue vehicles. Then we saw it: a C152, perched on the roof of a hangar. In order to get there, he had to leave the 75 ft wide runway, cross a wide grass strip to the taxiway, cross a wide ramp, and stall out onto the hangar roof. The soloing student was unhurt. He was damned lucky, he could easily have been killed if he hadn't had a convenient hangar roof to stall onto. Our flight school has been moving towards an all-new aircraft fleet. It it wise to be putting solo students out in a $170,000 airplane? IMHO, it is unwise to be putting solo students out in any sort of airplane if they don't "know when to go" (ie, know when to abort a landing and go around) and have a reasonable safety margin of proper reactions to a botched landing.

Student pilots are safer. Your fleet of
new 172's is in better hands than with a bunch of weekend warrior pilots who have to scrape the rust off their license when they go for a $100 hamburger once a month.

news A solo student (not mine) had a landing accident today. Landed on the nose wheel, porpoised a few times, and stalled the airplane in a slightly nose down attitude. The student was unharmed, but the aircraft is totaled. Had the student been trained specifically about porpoising? I ask because (as far as I can recall) porpoising was never mentioned before my solo, or even by the time I got my Private certificate. When I eventually did porpoise an airplane (C172), I didn't immediately understand what was happening. After the first bounce, the plane was just a few feet above the ground, and I expected it to settle down. After the second bounce, the porpoising was more pronounced, and I then recognized the phenomenon--not from my training, but from a cartoon I'd seen somewhere that showed a porpoising plane making progressively higher bounces before crashing nose-first. That changed my expectation of what was about to happen, just in time for the third bounce, which left me ten feet above the runway with the bottom starting to drop out. But that was a situation I'd been trained for, so I instantly added power and landed gently, with no damage. (I later learned that pulling way back on the yoke is a good way to stop the porpoising.) Our flight school has been moving towards an all-new aircraft fleet. It it wise to be putting solo students out in a $170,000 airplane? A student who isn't ready to risk a $170,000 plane isn't ready to risk her or his life. --Gary |

Stalls can occur in virtually any attitude and at virtually any airspeed. Attitude isn't the equivalent of angle of attack. Angle of attack depends on relative airflow, not attitude. It is a very minute, but important distinction. The aircraft can be stalled by gusting winds while in a relatively steep dive, or while in "cruise" attitude if it was reached from a dive too abruptly... Stall-speeds are approximations that GA'ers use because angle-of-attack gauges are uncommon, and because they provide an approximation based on ordinary performance envelope. Cheers, Kevin |

if they don't "know when to go"
Probably the instructor is at fault, sometimes, when they teach students how to "save" landings. The student isn't always capable of determining which should be saved, and which shouldn't. I know I scared myself once or twice as a student pilot. |
