## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain Bombardier Model DHC-8-100, DHC-8-200, and DHC-8-300 series airplanes. This proposed AD would require repetitive inspections of the fluorescent light tube assemblies of the cabin, lavatory, and sidewall, and corrective actions if necessary. This proposed AD would also provide for optional terminating action for the repetitive inspections. This proposed AD results from reports of overheating due to arcing between the fluorescent tube pins and the lamp holder contacts. The tubes had not been properly seated during installation. We are proposing this AD to prevent fumes, traces of visible smoke, and fire at the fluorescent light tube assembly.
