Once upon a time.................
There was an instructor (E.C.) at the former ATA (Airline Training Academy) at Orlando Executive Airport who knew everything and argued with all about everything. We (Chief Instructors) tried for a while to find a reason to can him, and he finally gave it to us.
On a dark, clear, Saturday night, he was in the pattern practicing night landings on rwy 07 with his student in an Aztec. During one approach, they forgot to lower the gear. As the props hit the pavement, the instructor initiated a go-around. They made left closed traffic, passed over the Fashion Square Mall (which was highly populated on Saturday nights with kids, parents, and such), turned left base over downtown Orlando (near the Sun Trust building, right on top of the then popular Church Street Station), and landed "without incident" in his words. They taxied the aircraft back to the ramp area, and parked the Aztec in it's appropriate spot like nothing happened.
As daylight came and the next business day began, it was enlightening. Both props had both tips bent backwards 90 degrees for at least the first 6 to 8 inches. The step on the right side was still there, but snapped out of it's mount so it freely swung back and forth. The ADF antenna (dome) was gone, the DME antenna, as well as the tail tie-down mount. Both engine cowlings had scrapes on the bottom.
He stated to us that he NEVER touched the ground, except for the props, and one of his "buddies" (F.G-P.) at the school also argued with us of the same, even though the "buddy" wasn't even at the school when it happened. He felt that it was in his best interest to go around and save the aircraft. He stated that the aircraft handled "perfectly normal", and had no clue that he even hit the pavement with the props (this was said even after we started up the engines and the whole aircraft wanted to shake itself apart). He never once thought about the highly populated areas of the Home Depot on the upwind, the intersection of Colonial Drive and State Hwy 436, the Mall, Church Street Station and all of the downtown bars, the neighborhood on final, etc. After that statement and the ensuing arguments, we finally had the correct opportunity to rid ourselves of him. The firing had nothing to do with the gear-up; it had all to do with the decision making process that he's lucky didn't totally fail on him (i.e. slamming into a mall on a Saturday night with upwards of 1,000 people in it, etc.), and the ensuing arguments. There were other gear-ups there; in fact, it seemed like the plague for a while. Two of the other gear-ups kept their jobs, simply because of admitted guilt and correct decision making.
Long story short, pull the mixture(s) and plant the thing on the ground. You already screwed up the engines by prop-striking them. They now HAVE to be overhauled or replaced, regardless. This latest accident is a prime example of what could happen. Luckily, in ORL, it didn't and numerous lives were spared.
