Narrative:

Cpr X was cleared to land runway 28 at tuc and small aircraft Y was cleared to stop and go runway 18. Small aircraft Z, 8 mi southwest of airport, got stuck microphone on 124.2 local frequency. Small aircraft Y was given short delay on runway 18 and slow to takeoff. Both cpr X and small aircraft Y is critical phase of flight to proceed with any other plan. The stuck microphone delayed clrncs shortly. Frequency was clear for short time prior to occurrence. Cpr X crossed over #south of runway 28 as small aircraft Y was in intersection of 2 runways. Approximately 5000' between 2 aircraft.

Original NASA ASRS Text

Title: CPR X HAD LESS THAN STANDARD SEPARATION FROM SMA Y ON LNDG. SYSTEM ERROR.

Narrative: CPR X WAS CLRED TO LAND RWY 28 AT TUC AND SMA Y WAS CLRED TO STOP AND GO RWY 18. SMA Z, 8 MI SW OF ARPT, GOT STUCK MIC ON 124.2 LCL FREQ. SMA Y WAS GIVEN SHORT DELAY ON RWY 18 AND SLOW TO TKOF. BOTH CPR X AND SMA Y IS CRITICAL PHASE OF FLT TO PROCEED WITH ANY OTHER PLAN. THE STUCK MIC DELAYED CLRNCS SHORTLY. FREQ WAS CLR FOR SHORT TIME PRIOR TO OCCURRENCE. CPR X CROSSED OVER #S OF RWY 28 AS SMA Y WAS IN INTXN OF 2 RWYS. APPROX 5000' BTWN 2 ACFT.
