Safety report about a recurring maintenance error

A licensed aircraft maintenance engineer submits a confidential safety report through the operator's SMS describing a recurring error: on three occasions in two months, panels on the upper wing surface were left with fasteners not fully secured after fuel tank access. In each case the error was caught by the next shift, but the engineer says the pressure to release aircraft on time is intense, that the same two technicians were involved, and that supervisors have told staff not to 'create paperwork'.
