Air rescue crews are searching the Sierra mountains for a light single engine aircraft that was expected to land at the Petaluma Municipal Airport on Monday night.

The plane, a Socata TB-20 Trinidad, left the Truckee-Tahoe Airport in Truckee just before 4 p.m. on Monday with two people on board, according to statement released Tuesday afternoon by the Civil Air Patrol, the all-volunteer civilian auxiliary of the United States Air Force.

Lt. Col. Crystal Housman of the Civil Air Patrol said Tuesday afternoon that a Civil Air Patrol single engine Cessna and a California Highway Patrol helicopter were assisting in the search.

The plane is registered to William H. Sherlock of Santa Rosa, who was listed in FAA records as a co-owner.

Family members reported that the aircraft had not arrived Monday night, the Civil Air Patrol said. The four-seat low-wing aircraft is blue with white with gold trim and is equipped with a 406 megahertz emergency locater transmitter, officials said.

No satellite hits have come in from the beacon, the air patrol said.

Know Your Rights

California law prohibits lawyers or others acting on behalf of a lawyer from:

— Soliciting clients at an accident scene, at a hospital, or on the way to a hospital.

— Soliciting clients who, due to their physical, emotional or mental state, may not be able to have reasonable judgment about the hiring of an attorney .

— Seeking clients by mail unless the letter and envelope are clearly labeled as an advertisement.

— Promising a particular outcome from legal representation.

In the wake of the fires, there is also the risk of victims being approached by people posing as attorneys. Consumers should determine if they are legitimate and licensed to provide legal services. Before hiring an attorney, look up their name or State Bar number on the State Bar website — www.calbar.ca.gov — to check the status of their license to practice law and whether they have any record of discipline.
