Pilot flying DHC-6 aircraft reported cabin door departed inflight.
Pilot narrative
Verbatim, de-identified by NASA. Placeholders: ZZZ,
X, Y.
Upon departing ZZZ to the south southeast for skydiving operations, I leveled the aircraft to maintain vertical separation from a cloud layer. After leveling the aircraft, I proceeded in the same direction towards an area of no cloud cover. I believe leveling/increasing speed of the aircraft while having the passenger window open in the cockpit, created unequal pressure and caused the sliding door to implode. I immediately reduced speed and began to change direction back towards ZZZ. The imploded door then exited the aircraft, striking the horizontal stabilizer and fell to the surface in pieces into what appeared to be a wooded area. After landing safely I proceeded to scout the area where the debris landed in another airplane. No debris, damage, gatherings or any activity regarding the incident were observed.
