Narrative: The aircraft was assigned a 12-month inspection; which consisted of several tasks; along with a Line Check and Routine Check. They told me that they didn't need tools to drop the bins because they were just going to sign it off. Prior to departing the office I glanced at the paperwork and noted aircraft was assigned a 12-month inspection; which consisted of several tasks; along with a Line Check and Routine Check. I took my tool box out to the A/C because of the Routine Check requiring panels to be opened for the proper servicing of the generators and to assist with the 12-month inspection. I offered my tools to two technicians to use to drop the wheel-bins so that they could do the fuel-shut-off inspections for the left and right engines and for the APU. They told me that they didn't need tools to drop the bins; because they were just going to sign it off. I didn't think that they were serious about not complying with the task; so I proceeded in servicing the generators; engine oils; and doing the FOQA (Flight Operations Quality Assurance) download in the aft equipment bay because one of the technicians didn't want to do it. After I finished the FOQA I removed all the tools; and closed up the aft equipment bay. During the time we were out at the aircraft; I never saw anyone go to the aft equipment bay or to the wheel-bins to do any of the 12-month checks. One of the leads working that night came out to see how things were progressing and I told him what was said. He asked me if I needed anything; and I told him that I was fine. He asked me where the other mechanics were and I told him that they were in the cabin doing something. After I had completed the Line and Routine check on the outside; I went into the aircraft to assist the mechanics with the rest of the 12-month inspection. They told me that they were done and that they just wanted [to] hang out in the aircraft for 30 min to make it look like they were working. They pulled out their phones and started to play games on them. I remained with the aircraft until we returned to the office to do paperwork. The night progressed as normal; the paperwork was signed off; and the mechanics never returned to the aircraft to drop the bins to comply with the inspections. They remained in the office for the remainder of the shift. I proceeded to inform my supervisor and he said that he would look into it.
