American Airlines Flight 1572, registration N566AA, was a McDonnell Douglas MD-83 flying from Chicago O'Hare that was damaged while landing short of runway at Hartford's Bradley International Airport on November 12, 1995.
Flight 1572 was enroute from Chicago O'Hare to Hartford's Bradley International Airport on November 12, 1995. The flight departed O'Hare over 90 minutes late due to bad weather and delayed connecting passengers. Enroute the flight received an ACARS printout for the weather at Hartford. It noted altimeter setting of 29.42 inches of mercury (996 hPa) adding that pressure was falling rapidly in the area. Before making their final approach they were further advised of a wind shear warning and severe thunderstorms for Hartford. Winds were now out of 170° at 29 knots (15 m/s) gusting to 39 knots (20 m/s). The First Officer checked the ATIS automated weather broadcast for Hartford which reported an altimeter setting of 29.40 inHg (996 hPa). For reasons unknown he entered this as 29.47 inHg (998 hPa) on the altimeter causing it to read approximately 70 feet (21 m) high. The Captain checked the weather radar before beginning the non precision approach to runway 15. It showed no convective cells on their path and he turned it off. As Flight 1572 began its final approach they were advised that the control tower was closing temporarily due to severe weather buckling a window inside the cab. The tower supervisor remained behind to assist the flight. The Captain noticed the autopilot was having difficulty maintaining altitude and heading in the buffeting winds. Five miles from the airport the plane encountered heavy rain and some turbulence. The flight continued descending to 908 ft (277 m), the minimum descent altitude (MDA) for the approach. This was likely 838 ft (255 m) due to the incorrect altimeter setting. As they began searching for the airport the plane continued descending.
At some point during the descent, the sink rate alarm went off immediately followed by a loud thump as the plane began shearing off treetops along Peak Mountain ridge. It was later estimated the plane was at 770 ft (230 m) elevation at this point. The Captain advanced the throttles full but the trees had been ingested into the engines causing them to flame out and shut down. The Captain immediately lowered flaps to 40° hoping it would momentarily cause the plane to "balloon" upwards. While not standard operating procedure it worked to a limited extent until the plane clipped a tree near the end of the runway. The plane then impacted the runway 33 ILS antenna equipment at the approach end of runway 15 before rolling to a stop with only one passenger sustaining minor injury.

0049:41 | APR: | American fifteen seventy-two, you're five miles from MISTR. Cross MISTR at or above three thousand five hundred, cleared for the VOR runway one five approach. |
0049:49 | RDO-2 | OK we'll uh, we're cleared for the approach. And we'll cross MISTR at or above uh, thirty-five hundred. American fifteen seventy-two. |
0049:55 | CAM-1: | Set. Comin' down. |
0049:57 | APR: | American fifteen seventy-two, roger and uh, be advised uh, the tower is closed at this time. It's a, temporary closure, due to uh, problem with uh one of the windows uh, so I'll need a uh, a down uh time on you but you can stay on this frequency uh, for that. |
0049:59 | CAM: | [Sound similar to stabilizer in motion horn] |
0050:16 | RDO-2 | Roger and, what happened on the window? |
0050:19 | APR: | It's just loose. They've got carpenters up there now boarding it up ... |
0050:23 | CAM-2: | It blew out. |
0050:23 | APR: | ... but once that's done the tower should open. |
0050:25 | RDO-2 | Copy. |
0050:28 | CAM-1: | Flaps eleven, please. |
0050:30 | CAM-2: | You got it. |
0050:34 | CAM: | [Sound of rattling similar to aircraft going through turbulence] |
0050:51 | CAM-2: | OK, five hundred feet, looking good, you can go down to, step down to two thousand by five miles. But then it ... |
0050:58 | CAM-1: | What's your **? |
0051:03 | CAM-2: | I think it's gonna be smoother once we get out of the weather. |
0051:05 | CAM-1: | Yeah. |
0051:10 | CAM-2: | OK, you're at thirty-five hundred *. |
0051:16 | CAM-1: | OK, we're cleared down to where? |
0051:17 | CAM-2: | You're cleared down to two thousand MSL at DILLN. By DILLN ... |
0051:21 | CAM-1: | OK, two thousand set and armed. |
0051:22 | CAM-2: | ... five miles * so it's good. Two thousand is set and armed. |
