Narrative:
We were descending at normal descent speed on the valre two arrival to land at hpn, when we heard a 'thud.' immediately the left engine 'oil pressure low' light came on. The oil pressure gauge was falling through 20 psi and heading rapidly toward zero. We shut down the left engine, declared an emergency, advising ATC the left engine was shut down, and requested vectors to bdl. (A line of thunderstorms was approaching hpn, and I was concerned it would be too close.) I used the short en route time to accomplish the appropriate checklists and advise the passenger. I requested fire equipment be standing by at bdl. We flew over the airport for a left downwind pattern and a successful landing on runway 24. Upon examination, we discovered that the outer, left main gear door had broken loose, punctured the inboard side of the left engine cowling, rupturing 3 metal oil lines. Gear extension had been normal. Although very busy handling this emergency, all went smoothly and well controled. I attribute this to: 1) a well trained crew. Reoccurring simulator training with flight safety company. 2) CRM training. The first officer focused on flying the aircraft while I worked checklists, ATC, and informing passenger. Each knew what to do and we worked as a team. 3) excellent cooperation from ATC.

Title: A SABERLINER-65 AT FL210 IN DSCNT EXPERIENCED THE L MAIN LNDG GEAR OUTER DOOR DEPART THE ACFT STRIKING THE L ENG LOWER COWLING SEVERING 3 ENG OIL LINES CAUSING LOSS OF OIL AND ENG SHUTDOWN.
Narrative: WE WERE DSNDING AT NORMAL DSCNT SPD ON THE VALRE TWO ARR TO LAND AT HPN, WHEN WE HEARD A 'THUD.' IMMEDIATELY THE L ENG 'OIL PRESSURE LOW' LIGHT CAME ON. THE OIL PRESSURE GAUGE WAS FALLING THROUGH 20 PSI AND HEADING RAPIDLY TOWARD ZERO. WE SHUT DOWN THE L ENG, DECLARED AN EMER, ADVISING ATC THE L ENG WAS SHUT DOWN, AND REQUESTED VECTORS TO BDL. (A LINE OF TSTMS WAS APCHING HPN, AND I WAS CONCERNED IT WOULD BE TOO CLOSE.) I USED THE SHORT ENRTE TIME TO ACCOMPLISH THE APPROPRIATE CHKLISTS AND ADVISE THE PAX. I REQUESTED FIRE EQUIP BE STANDING BY AT BDL. WE FLEW OVER THE ARPT FOR A L DOWNWIND PATTERN AND A SUCCESSFUL LNDG ON RWY 24. UPON EXAMINATION, WE DISCOVERED THAT THE OUTER, L MAIN GEAR DOOR HAD BROKEN LOOSE, PUNCTURED THE INBOARD SIDE OF THE L ENG COWLING, RUPTURING 3 METAL OIL LINES. GEAR EXTENSION HAD BEEN NORMAL. ALTHOUGH VERY BUSY HANDLING THIS EMER, ALL WENT SMOOTHLY AND WELL CTLED. I ATTRIBUTE THIS TO: 1) A WELL TRAINED CREW. REOCCURRING SIMULATOR TRAINING WITH FLT SAFETY COMPANY. 2) CRM TRAINING. THE FO FOCUSED ON FLYING THE ACFT WHILE I WORKED CHKLISTS, ATC, AND INFORMING PAX. EACH KNEW WHAT TO DO AND WE WORKED AS A TEAM. 3) EXCELLENT COOPERATION FROM ATC.
