Narrative: I had taken an AOG (Aircraft on Ground) squawk -'After selecting the landing gear handle down there is a loud bang in the nose gear area. The nose gear takes a normal amount of time to go down and no associated CAS (Crew Alerting System) messages are visible;' I had applied for a ferry flight in our portal as would be normal. Later that evening I was informed by my Maintenance Duty Manager operations had changed my request to a gear up ferry flight; I did ask why; [the manager] did send me guidance from our fleet supervisor a chart from the chief pilot with a specific chart to follow which I already had but still requested; then I also received a letter from [the aircraft manufacturer] dated to our domicile; Fleet Program Director and VP Safety that was not part of [Maintenance Control] original guidance; but after reading this letter I spoke to the Duty Manager and explained my stance with this whole issue and placed in the ferry flight line and added a status note.The next day back at work I was ordered personally via e-mail from my Fleet Supervisor to have tech complete a gear up ferry flight inspection and re-send the [Flight Check] portal as such this discrepancy clearly meets the GEAR UP ferry criteria developed by [the company]; so I did as I was told.Please keep in mind that all of these crew squawks I have taken in the past and phone conversations they said the words such as 'bang; a loud bang; a loud clunk; the bang startled both of us' etc. The letter from [the aircraft manufacturer] as I read it I could not help but notice and question that there are no references of 'loud bang heard/felt etc.' anywhere in either document.I found it very misleading and deceiving for the letter from [the aircraft manufacturer] to merely state 'louder than normal' or 'noisy or desynchronized landing gear extension' this is even more reason for me to scrutinize during my decision making process here in [Maintenance Control] as now I was not so sure these [aircraft manufacturer] flight ops people even saw the video. I did not take it lightly to write that status note in ferry line; I thought it through completely and my decision was not to fly aircraft gear up. But was overruled over guidance I still do not agree with.I caution flying our aircraft gear up with the known gear such as this particular problem is now seems a calculated risk that is acceptable as a new standard. Industry safety and warning terms come to mind such as the 'dirty dozen.' [The company] 20/20 flight plan safety and goal 'zero mishaps' 'the stop sign goes up after the accident' or 'the 'o' rings will fail below 40 degrees.'




Synopsis: Technician reported requesting a gear down ferry flight due to a problem with nose landing gear extend mechanism but is over ridden by Supervisor.
