What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
The pilot took off from runway 5R at rdu. This was the first flight after an oil change. At 3,500', the pilot noticed low oil pressure. He contacted rdu approach to return to rdu. He was cleared for runway 32 but requested 23L, which he was given. He then noticed an acrid smell, and declared an emergency. Soon after that his engine seized and his propeller stopped. He realized he wasn't going to make the airport, and landed on I-540 north of rdu. He stated that he had to wait to extend the gear because he needed all glide distance possible to land. The gear was in transit when he landed. He landed safely with minimal damage to the airframe, though the engine was destroyed due to loss of oil. Upon further inspection, it was determined that the wrong oil quick drain valve was installed on the aircraft during its oil change. When the gear retracted, it contacted the drain, expressing it, releasing all of the oil from the engine, causing the engine failure.
