If aircraft maintenance requires an oil level check, how long must the AMAD have been cooled down?

For an oil level check on the AMAD (Airframe Mounted Accessory Drive) in the F/A-18 E/F, it is essential to allow adequate cooling time to obtain an accurate reading. The recommended cooling period is 5 minutes. This duration ensures that the oil settles to its proper level, allowing for a precise measurement without the influence of residual heat, which could otherwise cause inaccuracies due to oil expansion.

The cooling period also serves to prevent burns or other hazards for personnel performing the maintenance. A shorter period, such as 2 minutes, would not allow the oil to cool sufficiently and therefore could lead to misleading measurements. Similarly, while longer durations like 10 or 15 minutes might provide even more cooling, they are unnecessary and could delay maintenance processes, making 5 minutes the optimal and standardized time for achieving accurate results.
