Narrative:
Normal engine start and normal indications on taxi and takeoff. 2-3 mins after takeoff (about 3-4 NM northeast of hro), master warning lighted with a #2 engine low oil pressure light. The engine was secured, checklist followed, and ATC was notified that we were returning to hro because we had lost an engine. The approach and landing were normal. Upon inspection, I found that the engine dipstick had not been secured properly. Although we lost several quarts of oil, a subsequent oil filter and metallic particle inspection showed that no damage resulted. I believe that the problem arose because of a number of factors, namely, my first officer seems to be under a lot of stress and it was an early am 'show' time. We fly 2 pilot crews as a rule. Although preflight was his responsibility, I understand that the entire flight was my responsibility. Realistically, though, I cannot follow an individual and do both pilots' jobs.

Title: A CORPORATE JET FLC RECEIVED A #2 LOW ENG OIL PRESSURE INDICATION AFTER TKOF AND RETURNED TO THE DEP ARPT. AFTER LNDG THE RPTR DISCOVERED THAT THE ENG OIL DIPSTICK HAD NOT BEEN SECURED. NO DAMAGE WAS FOUND IN A SUBSEQUENT INSPECTION.
Narrative: NORMAL ENG START AND NORMAL INDICATIONS ON TAXI AND TKOF. 2-3 MINS AFTER TKOF (ABOUT 3-4 NM NE OF HRO), MASTER WARNING LIGHTED WITH A #2 ENG LOW OIL PRESSURE LIGHT. THE ENG WAS SECURED, CHKLIST FOLLOWED, AND ATC WAS NOTIFIED THAT WE WERE RETURNING TO HRO BECAUSE WE HAD LOST AN ENG. THE APCH AND LNDG WERE NORMAL. UPON INSPECTION, I FOUND THAT THE ENG DIPSTICK HAD NOT BEEN SECURED PROPERLY. ALTHOUGH WE LOST SEVERAL QUARTS OF OIL, A SUBSEQUENT OIL FILTER AND METALLIC PARTICLE INSPECTION SHOWED THAT NO DAMAGE RESULTED. I BELIEVE THAT THE PROB AROSE BECAUSE OF A NUMBER OF FACTORS, NAMELY, MY FO SEEMS TO BE UNDER A LOT OF STRESS AND IT WAS AN EARLY AM 'SHOW' TIME. WE FLY 2 PLT CREWS AS A RULE. ALTHOUGH PREFLT WAS HIS RESPONSIBILITY, I UNDERSTAND THAT THE ENTIRE FLT WAS MY RESPONSIBILITY. REALISTICALLY, THOUGH, I CANNOT FOLLOW AN INDIVIDUAL AND DO BOTH PLTS' JOBS.
