True or False: It is advisable to detach the air line from the drill before changing the drill bit.

When changing the drill bit, it is advisable to detach the air line from the drill for safety reasons. Detaching the air line ensures that there is no accidental activation of the drill during the bit change, which can lead to personal injury or damage to the equipment. Keeping the drill in a safe and non-operational state while performing maintenance tasks is a crucial safety practice in aerospace assembly and similar environments.

Selecting to keep the air line connected exposes the technician to unnecessary risks, as the drill could inadvertently start while they are handling the bit. Therefore, it's best practice to perform such maintenance procedures with the air line detached.
