"Attention, all aircraft listening . . . there‘s a -little rainshower just north of the airport 'and they‘re starting to make ILS [instrument landing system] approaches . . . tuneup one oh nine one for one seven left." ' . ' . .
_ At 1759:47, the first officer stated, "We're gonna get our airplane washed," and at 1759:54, the captain switched to Regional Approach Control's ArrivalRadar‘el (AR-1) frequency and told the controller that they were at 5,000 feet. AT 1800:36,'the approach controller asked American Air Lines flight 351 if it was able to see the airport. (Flight 351 was two airplanes ahead of flight 191 in the landing sequence for runway 1'17L.) Flight 351 replied, "As soon as we break out of this rainshower we will." The controller then told flight 351 that it was 4 miles from the outer marker, and to join the localizer at 2,300 feet; the controller then cleared the flight for the ILS approach to runway 17L.' All . of the transmissions between the controller and flight 351 were recorded on flight 191's CVR.
At 1800:51, the approach controller asked flight 191 to reduce'its airspeed to 170 knots indicated (KIAS), and to turn left to 270°; flight 191 then acknowledged receipt of. the clearance. Flight 191 .had been sequenced behind a Learjet Model 25 (Lear 25) for landing on runway 17L. . '
At 1802:35, the approach controller told flight 191 that it was 6 miles from the outer marker, requested that it turn to 180° to join the localizer at or above 2,300 feet, and stated, "cleared for ILS one seven left approach." The flight acknowledged receipt of the transmission. At 1803:03, the approach controller requested flight 191 "to reduce your speed to one six zero please," and the captain replied, "Be glad to." Thereafter, at 1803:30, he broadcast, "And we're getting some variable winds out there due to a shower . . . out there north end of DFW." This transmission wasreceived by flight 191, and at 1803:34, the CVR‘s cockpit area microphone (CAM) showed that an unidentified flightcrew member remarked, "Stuff is moving in." ' .A
At 1803:46, the approach controller requested flight 191 to slow to 150 KIAS, and to contact the DFW Airport tower. At 1803:58, the captain, after switching to the tower's radio frequency, stated, "Tower, Delta one ninety one heavy, out here in thevrain, ' feels good." The tower clearedsthe flight to land and informed it, "wind zero nine‘z'er'o at five, gusts to one five." At 1804:07, the first officer called for the before-landing check. The flightcrew confirmed that the landing gear was down and that the flaps ;were extended to 33°, the landing flap setting. -
At 1804:18, the first officer said, "Lightning coming out of that one." The captain asked, "What," and the first officer zrepeated "Lightning coming out of that one." The captain asked, "Where," and at 1804:23, the first officer replied, "Right ahead of .us."
Flight 191 continued descending along the final approach course. At 1805:05 the captain called out "1,000 feet." At 1805:19, the captain cautioned-the first officer! to watch his indicated airspeed and a sound identified as rain began. At 1805:21, the captain ‘ warned the first officer, "You’re gonna lose it all of a sudden, there it is." At 1805:26 the captain stated, "Push it up, push it way up." At 1805:29, the sound of engines at high rpm was heard on the CVR, and the captain said "That's it."
