An aircraft auxiliary power unit assembly includes an aircraft skin (22) providing a cavity (11). The aircraft skin (22) is secured to a structure (13) in an assembled condition and provides an opening (60). An auxiliary power unit (10) is arranged within the cavity (11) and secured to the structure (13). The aircraft skin (22) substantially covers the auxiliary power unit (10) in the assembled condition. An inlet duct (18) is removably secured within the opening and is selectively connected to the auxiliary power unit between installed and service positions. The installed and service positions are with the aircraft skin (22) in the assembled condition. A method of servicing the auxiliary power unit includes removing the auxiliary power unit inlet duct (18) from the opening (50) in the aircraft skin (22). The auxiliary power unit (10) that is arranged within the cavity (11) of the aircraft skin (22) is exposed. A portion of the auxiliary power unit (22) is serviced through the opening (50).
