### Federa l Registe r 

### Pu b li catio n The FAA has determined that good cause exists for not publishing a summary of the petition in the Federal Regi ster for public comment because the requested amendment to th eexempt i o n wou ld not set a precedent , and an y de lay in actin g on thi s pet iti on wo uld be detrimental to Embrae r Mode l EMB- 545 and EMB- 550 a irplane fleet o perat ion s.
