NTSB Narrative Summary Released at Completion of Accident

At 1455:29, the pilot of N5ZA, a Moravan Z242L, called the Waukegan Regional Airport (UGN) air traffic control tower (ATCT) and reported 15 miles northeast for landing. The local controller (LC) acknowledged and queried N5ZA, "are you coming down the shoreline?" N5ZA responded, "That's affirmative." (Radar data showed that N5ZA was actually 4.5 miles east of the shoreline). The LC instructed the pilot to "report turning final at the shoreline for the straight in [to] runway two three." The pilot responded, "ok, straight in for two three, thanks." At 1457:57, the LC instructed N99063, a Cessna 172P, to taxi into position and hold," and, 10 seconds later, he cleared N99063 for takeoff. At 1459:48, the LC asked the pilot of N5ZA for his position. The pilot replied that he was "just about a mile or two off the lake...off the shoreline." (However, radar data showed that N5ZA was actually 3.75 miles off the shore along the runway 23 extended centerline and 2.7 miles from shore with the shoreline being abeam to the right side of the aircraft.) At 1459:53, the LC asked the pilot, "are you straight in still?" The pilot responded, "ah, yes sir." The LC instructed the pilot to "keep your speed up as much as feasible cleared to land." The pilot acknowledged and stated, "peddling as fast as I can." At 1500:38, the LC instructed N99063 to "continue on the downwind, advise when you see a red low wing aircraft straight in on final." The pilot of N99063 responded, "looking for traffic." (Radar data showed that N99063 was established on the downwind leg, approximately 0.7 miles due north of the approach end of runway 23. The radar also showed that N5ZA was 2.3 miles northeast of the shoreline, 6.3 miles from the approach end of runway 23.) At 1500:50, the pilot stated, "zulu alpha's the white zlin." The LC acknowledged and transmitted to N99063, "it'll be a white low wing aircraft." The pilot of N99063 acknowledged. At 1501:16, the pilot of N99063 stated, "negative traffic," and asked the LC to advise her when to turn for her base leg. The LC acknowledged. (Radar data showed that N99063 was 1.75 miles northeast of the approach end of runway 23 and that N5ZA was 1.4 miles northeast of the shoreline, 5.3 miles from the approach end of runway 23.) At 1501:41, the LC asked the pilot of N5ZA how far out he was from the shoreline; the pilot responded that he was "just crossing the shoreline." (Radar data showed that N5ZA was 0.8 miles from the shoreline, approximately 4.8 miles from the approach end of runway 23.) At 1502:09, the LC asked the pilot of N99063 if she saw N5ZA yet. The pilot of N99063 responded, "negative." The LC asked the pilot of N99063, "have you passed the shoreline?" The pilot of N99063 replied, "gettin there." (Radar data showed that N99063 was 1.6 miles from the shore along the extended downwind leg for runway 23's right-hand traffic pattern.) At 1502:16, the LC instructed N99063 to "start your base leg now." The pilot of N99063 acknowledged. (Radar data showed N5ZA crossing the shoreline, 4 miles from the approach end of the runway 23. As the pilot of N99063 turned onto base leg, then final approach, the airplane was slightly in front of N5ZA.) At 1503:19, the pilot of N5ZA reported, "negative contact with the cessna in front of us." (Radar data showed that N5ZA was approximately 2.6 miles from the approach end of runway 23.) The LC replied, "you should be number one, Bob." At 1503:27, the pilot of N5ZA stated, "then we have the traffic in sight, thanks." (Radar data showed that N99063 established on final 2.5 miles from the approach end of runway 23.) At 1503:38, the LC instructed the pilot of N99063 to "advise when you turn final." The pilot of N99063 reported that she was on final approach. The LC said, "thank you." At 1503:53, the LC asked N5ZA, "do you see a cessna in front of you?" At 1504:00, the pilot of N5ZA responded, "[N5ZA] just had a midair." The LC responded, "we just saw that." (The last radar target from N5ZA was received at 1503:59 and showed that N5ZA was 2 miles from the approach end of runway 23.) Both airplanes came down in the city of Zion, Illinois. N5ZA impacted into the roof of a hospital, and subsequently exploded. N99063 struck a tree and a sidewalk before coming to rest on a residential street. Examinations of the wreckage of both airplanes revealed no anomalies.

NTSB Probable Cause Narrative

The pilot's failure to maintain clearance from the other airplane. Factors relating to the accident were the pilot's poor visual lookout, and the airport control tower local controller's failure to provide effective sequencing.
