It is the banning of the Piaggio P180 from the Santa Monica Airport because it is louder than 95dB 1500 feet from the end of the runway.
When is the Toronto Port Authority going to ban this incredibly noisy aircraft?

NOISE LEVEL LIMITS
As a result of an agreement between the City of Santa Monica and the FAA, an Airport Ordinance was established setting a maximum noise level of 95.0 dBA Single Event Noise Exposure Level (SENEL) measured at noise monitor sites 1,500 feet from each end Santa Monica Airport "Fly Neighborly Program" focuses on pilot education and cooperation. However, repeat violators of the noise limit shall be progressively fined ($2,000,$5,000,$10,000) and excluded from using the Airport.

Compliance with the Airport Ordinance is mandatory unless deviations are made necessary by weather, ATC instructions or clearances, an inflight emergency or other safety considerations.
