@valleydweller,
Quote:The statement stressed the recommendation to change the monitor "allows the operator full freedom to totally, partially or not at all apply it." When safety is at issue, the aircraft maker puts out a mandatory service bulletin followed up by an airworthiness directive, not a recommendation.
Yes, it's fine, ValleyD.
The statement [stressed] stated that the recommendation to change the monitor "allows the operator full freedom to totally, partially or not at all apply it [the recommendation]." In other words it's up to the operator of the jet to decide what to do.
At those times when safety is [at issue] paramount, the aircraft maker puts out a
mandatory service bulletin followed up by an airworthiness directive, not a recommendation. The operator of the jet is then required to make the changes.
