Form BOE-570-1, Supplementary Schedule to Form 571-L - Air Carriers Operation Report – Los Angeles County, CA

Form BOE-570-1, Supplementary Schedule to Form 571-L - Air Carriers Operation Report, is the schedule on which an air carrier reports flight detail for one airport during a calendar year: aircraft sub-fleet types, route pairs, number of flights, BOE flight time and ground time.

The printed title on the form is "Supplementary Schedule to the Business Property Statement, Air Carrier's Operation Report," and its heading reads "Flight Detail Activity Period Calendar Year." The form is issued through the Los Angeles County Office of the Assessor and is returned with the Business Property Statement.

The schedule has seven columns, A through G. They run from aircraft sub-fleet type and route pair, through the number of flights and the BOE flight time for each route, to the annual California BOE flight time in minutes, the total ground minutes, and the total minutes for the airport. A TOTAL line closes the table.

The result is not a standalone figure. The instructions say to add the total time calculated on this form to Form BOE 570-2 in order to calculate the allocation factor for each sub-fleet at each airport.

The Assessor's forms page lists several related air-carrier schedules, including BOE-570-2 (Flight Equipment Value Computation), BOE-570-3 (Air Carrier's Operation Report), BOE-570-FO-1 (Aircraft Cost) and BOE-570-FO-2 (Aircraft Value Computation), and the Business Property Statement itself as BOE-571-L.

Air carriers whose aircraft had activity at an airport during the prior calendar year use this schedule. The instructions on the form direct you to use a separate BOE-570-1 for each airport within each county where your aircraft had activity.

That means:

• one form per airport, even when the same carrier flew the same sub-fleet at several airports;
• one form per county where you had activity, because the form has its own COUNTY and AIRPORT entries;
• every aircraft sub-fleet type that had activity at that airport listed on the same form, in column A.

The form is a supplementary schedule to the Business Property Statement, so it is completed by the same carrier that files that statement. The form names no separate signer or representative, and it contains no signature block.

Form BOE-570-1 is returned with the Business Property Statement, so it is completed whenever you prepare that statement. The bottom of the form says "Return this form with the Business Property Statement," and no separate due date is printed on it.

The schedule reports activity from the prior calendar year: column A asks for sub-fleet types that had activity at the airport during that year, and column C counts the flights in that year. The Activity Period line at the top is where you enter the calendar year.

Have the latest "Letter to Assessors" at hand before you start, because column D takes its BOE flight times from the list published there. For the due date of the Business Property Statement itself, check the Los Angeles County Office of the Assessor's forms page at https://assessor.lacounty.gov/forms.

There is one route printed on the form: return it together with the Business Property Statement. BOE-570-1 gives no mailing address, portal or appointment rule of its own, so it follows the channels that apply to the Business Property Statement.

• With the Business Property Statement: attach the completed BOE-570-1 to the statement and send them as one package. The Los Angeles County Office of the Assessor lists the statement on its forms page at https://assessor.lacounty.gov/forms as BOE-571-L / ASSR-49.
• One form per airport: if your aircraft had activity at more than one airport, or in more than one county, include a separate BOE-570-1 for each.
• Companion schedule: add the total time calculated on BOE-570-1 to BOE 570-2 before you assemble the package.
