A maintenance controller recommends that APU compartments be checked any time an APU is MEL'd for failing to start. He had previously issued an MEL for the APU oil quantity indication on an md-11 aircraft that was later found to have sustained heat damage to an APU fire containment shroud and total loss of APU oil.

Narrative:
Issued MEL 49-20-01 after aircraft maintenance technician (amt) stated this was an oil indication problem only. The maintenance release states that the ZZZ amt noted the oil quantity was reading 0.0. The fire damage was noted two days later in ZZZ after ZZZ1 amt had serviced APU to full and tried to start APU. The damage could have been caused at that time. ZZZ amt suspected an oil indication problem and called maintenance control for a deferral. Per MEL 49-20-01 maintenance step-3; I issued the control number. [Recommend] inspecting the APU compartment every time we MEL an APU for failing to start. Routine maintenance.
