General Reporting Provisions—Large Certificated Air Carriers

Section 21 Introduction to System of Reports

(a) Each large certificated air carrier shall file with the BTS, monthly, quarterly, semiannually, and annually BTS Form 41 Reports of financial and operating statistics as prescribed herein unless waiver has been made by the BTS.

(b) The system prescribed provides for the submission by each air carrier of four classes of financial and operating statistics, on individual schedules of the BTS Form 41 Report, grouped as follows:

A. Certification.

B. Balance Sheet Elements.

P. Profit and Loss Elements.

T. Traffic and Capacity Elements.

(c) The prescribed system of reports provides that the frequency of reporting shall be monthly for some schedules, quarterly for some, semiannually for some and annually for others. It also provides in some areas for the classification of large certificated air carriers into Group I, Group II, and Group III with the form and content differentiated as between groups.

(d) Each schedule of the prescribed BTS Form 41 Report has been assigned a specific code. The prefix alphabetical codes A, B, P and T, respectively, have been employed to denote certification, balance sheet, profit and loss, and traffic and capacity. The digits immediately following the alphabetical prefix designate the particular schedule.

(e) [Reserved]

(f) [Reserved]

(g) Four separate air carrier entities shall be established for large certificated air carriers conducting scheduled service for the purpose of submitting the prescribed reports. They are as follows:

(1) Domestic operations;

(2) operations via the Atlantic Ocean;

(3) operations via the Pacific Ocean; and

(4) operations in Latin American areas. With respect to the first classification, the domestic entity shall embrace all operations within and between the 50 States of the United States, the District of Columbia, the Commonwealth of Puerto Rico and the U.S. Virgin Islands, and shall also include Canadian transborder operations. The reports to be submitted by each entity shall be comparable to those required of a distinct legal entity whether the reporting entity constitutes such an entity, a semiautonomous physically separated operating division of the carrier, or an entity established for reporting purposes only.

(h) Two separate entities shall be established for large certificated air carriers predominantly engaged in conducting charter activities for the purpose of submitting the prescribed reports:

(1) Domestic operations; and

(2) international operations. The domestic entity includes all operations within and between the 50 States of the United States, the District of Columbia, the Commonwealth of Puerto Rico, and the U.S. Virgin Islands. All other operations will be in the international entity.

(i) The entities for which separate reports shall be made by the different route and charter air carriers will be set semiannually by the Office of Airline Information.

(j) As a general rule separate reports shall be filed for the air carrier and for each associated company air carriers as defined in section 03 which is an air carrier. However, transactions of associated companies in which 100 percent equity control resides in the reporting air carrier shall be consolidated with transactions of the reporting air carrier when such associated companies perform services related to the transport operations of the reporting air carrier almost exclusively and are not engaged in air transportation for their own account.

(k) Generally, route air carriers' nonscheduled services shall be treated as an integral part of the reporting entity to which most closely related without regard to the geographic area in which such nonscheduled services may actually be performed. However, supplemental reports shall be made of nonscheduled services (including service for the Department of Defense) in areas not encompassed by the prescribed reporting entity in any month in which the available ton-miles of such nonscheduled services exceed 5 percent of the available ton-miles of the reporting entity. Such supplemental reports shall continue until waived by the BTS upon a showing that such nonscheduled operations will not in the subsequent 12-month period exceed the 5-percent limit. The supplemental reports to be filed each month or calendar quarter, as applicable, shall be comprised of report Schedules P-5, T-1, and T-2. Transport and nontransport revenues pertaining to such separately reported nonscheduled services shall be reported on Schedule P-2 each quarter.

(l) When and as required in the national interest, any air carrier which performs nonscheduled transport services for the Department of Defense shall, when directed by the Department, make separate reports for such services as if they were conducted by a physically separate transport entity, such reports shall consist of Schedules P-1 through P-7, T-1, and T-2. The letter “D” shall be inserted on such reports, following the schedule number of each P and T schedule. When a carrier has more than one reporting entity, nonscheduled transport and nonscheduled Defense services shall be assigned to the reporting entity to which more closely related.

1 Due dates falling on a Saturday, Sunday or national holiday will become effective the first following work day.
2 Reporting due dates on Form 41 Schedules B and P are extended to March 30 if preliminary schedules are filed at the Department by February 10

(b) Each large certificated air carrier shall file the applicable schedules of the BTS Form 41 Report with the BTS in accordance with the above instructions with the following exceptions:

(1) The time for filing B and P report schedules for the final quarter or semiannual period of each calendar year may be extended to the following March 30 if the preliminary Schedules B-1 or B-1.1 and P-1.1 or P-1.2 are submitted, as applicable, and are received on or before their respective due dates.

(2) For the third month of any calendar quarter, Schedule P-1(a) need not be filed if Schedule P-1.1 or P-1.2 for the quarter or semiannual period, as applicable, is received on the due date prescribed for Schedule P-1(a).

(3) Income and expense data on Schedule P-1(a) for each month will be withheld by the BTS from public disclosure, until such time as

(i) the semiannual or quarterly financial reports are due,

(ii) the semiannual or quarterly financial reports are filed, or

(iii) information covered by monthly reports is publicly released by the carrier concerned, whichever occurs first. Before that time, income and expense data reported on Schedule P-1(a) will be disclosed to parties to any proceeding before the DOT to the extent that such data are relevant and material to the issues in the proceeding upon a determination to this effect by the administrative law judge assigned to the case or by the DOT. Any data to which access is granted may be introduced into evidence, subject to the normal rules of admissibility of evidence. The DOT will make other disclosure of these data upon its own motion or upon application of any interested person, when the DOT finds the public interest so requires. The BTS may, from time to time, publish summary information compiled from Schedule P-1(a) in a form which will not identify the individual carrier. At the request of an air carrier, and upon a showing by such air carriers that public disclosure of its preliminary year-end report would adversely affect its interests and would not be in the public interest, the BTS will withhold such preliminary year-end report from public disclosure until such time as (i) the final report is filed, (ii) the final report is due, or (iii) information covered by the preliminary report is publicly released by the carrier concerned, whichever occurs first.

(c) If circumstances prevent the filing of a report on or before the prescribed due date, consideration will be given to the granting of an extension upon receipt of a written request therefor. To provide ample time for consideration and communication to the air carrier of the action taken, such a request must be delivered to the BTS in writing at least three (3) days in advance of the due date, setting forth good and sufficient reason to justify the granting of the extension and the date when the report can be filed. Except in cases of emergency, no such request will be entertained which is not in writing and received by the BTS at least three (3) days before the prescribed due date. If a request is denied, the air carrier remains subject to the filing requirements to the same extent as if no request for extension of time had been made.

(d) [Reserved]

(e) All financial data reported on B, P and G schedules shall reflect the status of the air carrier's books of account for the period for which the report is being made and shall conform to the instructions contained in this Uniform System of Accounts and Reports. At the option of the air carrier, Group III air carriers may round reported financial data to the nearest thousands of dollars by typing “($000)” at the top of each amount column. All Group I and Group II air carriers may, at their option, round reported financial data to the nearest whole dollars by dropping the cents. All rounded amounts must be balanced within and between schedules. This option applies only to the submission of hardcopy reports. Instructions for the submission of data in ADP format are contained in the Accounting and Reporting Directives, which are available from OAI.

(f) Traffic and other operational statistics included in schedules of the BTS Form 41 reports shall reflect data pertaining to the month, quarter or 12-months-to-date period for which the report is being made.

(g) Adjustments correcting errors in previously reported traffic and other operational statistics shall not be included in data reported in schedules for the current period but shall be effected by submission of corrected schedules for the period to which applicable or, if only a few items are involved, by written notice and authorization to the BTS to correct previously filed reports except that any correction which amounts to less than one-half of one percent (0.5%) of the corrected amount for the month to which related may be included in the report for the current month provided the amount of the correction is clearly noted on the Form 41 Report.

(h) All letters and statements of correction or revision of reported data shall be a part of the BTS Form 41 reports.

(i) All changes in accounting methods having a material impact upon the particular financial elements involved, and all changes in methods of computing and reporting traffic and capacity statistics having a material impact upon the particular statistic involved shall be adequately explained and identified in the report first reflecting such changes. Such explanations related to financial position or financial results shall be made on BTS Form 41 Schedule P-2. Changes in methods for computing or reporting traffic and capacity statistics shall be identified and explained on a separate sheet attached to the first report affected. (See sec. 2-16.) The reporting requirements shall not be construed, in any sense, as relieving the air carrier of the responsibility for conforming its procedures to those otherwise prescribed in this system of accounts and reports.

(j) All financial statements released by carriers to the public reflecting a financial position or operating results for dates or reporting periods not covered by reports on file with the BTS shall be filed with the Board simultaneously with their public release.
