This is a usual scenario especially where the aircraft owner feels that the aircraft is safer even without compliance. In fact, if a service bulletin doesnât have an airworthiness directive, the FAA doesnât deem its recommendations to be mandatory or necessary.

A childâs weight status is determined using age-and sex-specific BMI percentiles. Children with BMIs in the 85â94th percentiles on BMI-for-age growth charts are considered overweight; children with BMIs at the 95th percentile or higher are obese. BMI does not distinguish between fat and lean body mass.
