Narrative:

I am an fpl at dsm ATCT/TRACON. The incident involved air carrier X aircraft. 2 controllers were on duty; 1 fpl, 1 developmental, midshift, air carrier X blew a tire. All this has been reported. What concerns me is the staffing on mid shifts at dsm ATCT. It is at min with 2 controllers, and during the incident the fpl/controller in charge called her supervisor at home and was later berated for asking for help. Dsm is busy 4 nights a week on the mids. Now, dsm is planning to reduce staffing on those mids to one fpl. This is highly dangerous. 1 person cannot handle radar, tower, ground and clearance as well as act as supervisor. I speak from experience. It is an unsafe operation. 2 controllers should be the min or better. 1 fpl and 2 supervisor. Supplemental information from acn 185868. Air carrier X cleared for visual 30R at 10 mi out. Normal descent, speed reduction, flap and gear extension. No rain on approach or landing, but down poor, steady, vertical rain second half of runway. Runway damp previous rains. 150-200 ft AGL airspeed increase 20 KTS to 160 KTS (speed maintained). 50-80 ft AGL severe roll then vertical oscillations to point of aircraft almost out of control and potential wing tip ground contact. Uneventful and surprisingly smooth landing approximately 1500 ft down runway. Normal slow down and braking. At 80-100 KTS approximately felt antiskid releasing and lights so indicated. Normal taxi and parking. 10 min after, parked at gate, no passenger, ground personnel, or crew on board #3 tire blew damaging surrounding area. #2 tire threw tread (pieces found on runway 1000-1500 ft, from aircraft turn off. 3200 ft from end of runway. Our turn off and 1500 ft of runway left). Suspect tread hit hub and damaged antiskid, causing both ib tires to lock and flat spots which then blew. No injuries. Damage at gate while parked and #3 tire blew.

Narrative: I AM AN FPL AT DSM ATCT/TRACON. THE INCIDENT INVOLVED ACR X ACFT. 2 CTLRS WERE ON DUTY; 1 FPL, 1 DEVELOPMENTAL, MIDSHIFT, ACR X BLEW A TIRE. ALL THIS HAS BEEN RPTED. WHAT CONCERNS ME IS THE STAFFING ON MID SHIFTS AT DSM ATCT. IT IS AT MIN WITH 2 CTLRS, AND DURING THE INCIDENT THE FPL/CIC CALLED HER SUPVR AT HOME AND WAS LATER BERATED FOR ASKING FOR HELP. DSM IS BUSY 4 NIGHTS A WK ON THE MIDS. NOW, DSM IS PLANNING TO REDUCE STAFFING ON THOSE MIDS TO ONE FPL. THIS IS HIGHLY DANGEROUS. 1 PERSON CANNOT HANDLE RADAR, TWR, GND AND CLRNC AS WELL AS ACT AS SUPVR. I SPEAK FROM EXPERIENCE. IT IS AN UNSAFE OP. 2 CTLRS SHOULD BE THE MIN OR BETTER. 1 FPL AND 2 SUPVR. SUPPLEMENTAL INFO FROM ACN 185868. ACR X CLRED FOR VISUAL 30R AT 10 MI OUT. NORMAL DSCNT, SPD REDUCTION, FLAP AND GEAR EXTENSION. NO RAIN ON APCH OR LNDG, BUT DOWN POOR, STEADY, VERT RAIN SECOND HALF OF RWY. RWY DAMP PREVIOUS RAINS. 150-200 FT AGL AIRSPD INCREASE 20 KTS TO 160 KTS (SPD MAINTAINED). 50-80 FT AGL SEVERE ROLL THEN VERT OSCILLATIONS TO POINT OF ACFT ALMOST OUT OF CTL AND POTENTIAL WING TIP GND CONTACT. UNEVENTFUL AND SURPRISINGLY SMOOTH LNDG APPROX 1500 FT DOWN RWY. NORMAL SLOW DOWN AND BRAKING. AT 80-100 KTS APPROX FELT ANTISKID RELEASING AND LIGHTS SO INDICATED. NORMAL TAXI AND PARKING. 10 MIN AFTER, PARKED AT GATE, NO PAX, GND PERSONNEL, OR CREW ON BOARD #3 TIRE BLEW DAMAGING SURROUNDING AREA. #2 TIRE THREW TREAD (PIECES FOUND ON RWY 1000-1500 FT, FROM ACFT TURN OFF. 3200 FT FROM END OF RWY. OUR TURN OFF AND 1500 FT OF RWY LEFT). SUSPECT TREAD HIT HUB AND DAMAGED ANTISKID, CAUSING BOTH IB TIRES TO LOCK AND FLAT SPOTS WHICH THEN BLEW. NO INJURIES. DAMAGE AT GATE WHILE PARKED AND #3 TIRE BLEW.
