(a) The certification of the BTS Form 41 Report shall be signed by an elective corporate officer, executive, or director. Other persons may be authorized by the carrier to sign the certification provided a written authorization disclosing the individual's name and title is forwarded to the Department of Transportation. Since corrections or revisions of reported data are a part of the BTS Form 41 Report, all correspondence relating to such matters shall be signed only by the person(s) authorized to sign the certification.

(b) The certification of the Form 41 reports, embodied in Schedule A thereof, shall read as follows:

I, the undersigned (Title of officer in charge of accounts) ____ of the (Full name of the reporting company) ___ do certify that this report and all schedules, ADP-media submissions, Passenger Origin-Destination Survey submissions and supporting documents which are submitted herewith or have been submitted heretofore as parts of this report filed for the above indicated period have been prepared under my direction; that I have carefully examined them and declare that they correctly reflect the accounts and records of the company, and to the best of my knowledge and belief are a complete and accurate statement, after adjustments to reflect full accruals, of the operating revenues and expenses, income items, assets, liabilities, capital, retained earnings, and operating statistics for the periods reported in the several schedules, the Schedule T-100 ADP-media submissions, and the Passenger Origin-Destination Survey; that the various items herein reported were determined in accordance with the Uniform System of Accounts and Reports for Large Certificated Air Carriers prescribed by the Department of Transportation; and that the data contained herein are reported on a basis consistent with that of the preceding report except as specifically noted in the financial and statistical statements.

(a) This schedule shall be filed by all Group II and Group III air carriers and Group I air carriers that have annual operating revenues of $20 million or more.

(a) This schedule shall be filed semiannually by Group I air carriers with annual operating revenues below $20 million.

(b) Each carrier shall insert in the space provided for “OAG Code” its carrier code as contained in the Official Airlines Guide (OAG). If the OAG does not contain a carrier code for the reporting carrier, a code will be provided by the Office of Airline Information upon request. This code will then be inserted in the space provided for “carrier code.”

(c) This schedule shall show the account balances at the close of business on June 30 or December 31, as applicable, of each semiannual reporting period.

(d) “Current Assets” shall include all resources that may reasonably be expected to be realized in cash or sold or consumed within one year. This group of assets is classified into three basic accounts:

(1) “Cash and Equivalents” shall include cash on hand and on deposit, U.S. Government securities, and other temporary cash investments.

(2) “Notes and Accounts Receivable-Net” shall include general traffic accounts receivable, government receivables, notes and receivables from associated companies, officers, employees and others, and a deduction for a reasonable allowance for bad debts.

(3) “Other Current Assets” shall contain all other current assets not provided for in the above classifications. This account shall include, but is not limited to, short-term prepayments, expendable spare parts, supplies and other inventories of flight equipment replacement parts that are usually replaced rather than repaired, and materials and supplies held in stock, such as fuel and oil, expendable tools, office supplies and food service supplies. Spare parts may be reduced by an allowance for obsolescence to provide for losses in value.

(f) “Other Assets” shall included all assets not included in the above categories, such as long-term investments, long-term prepayments, long-term receivables, deferred charges, intangible assets, equipment purchase deposits, and construction work in progress.

(g) “Current Liabilities” shall include all obligations, the liquidation of which is reasonably expected to require the use of existing resources within one year. This group of liabilities is classified into three basic accounts:

(1) “Notes and Accounts Payable” shall include any payments on long-term debt, short-term notes and accounts payable, and accrued expenses that are payable within one year.

(2) “Accrued Taxes” shall include tax liabilities, such as those imposed on income, property and payroll, which are reasonably expected to be liquidated within one year.

(3) “Other Current Liabilities” shall include all current liabilities which are not provided for elsewhere, such as air traffic liabilities for unused transportation sold (includes sales of transportation on both the reporting carrier and other carriers).

(m) All substantive matters that may materially influence interpretations or conclusions in regard to the financial condition or the earnings position of the air carrier which are not clearly identified in the body of the schedule or which represent information that cannot be expressed adequately in monetary terms shall be completely and clearly stated in a note attached to this schedule and cross-referenced to the affected account or accounts.

(a) This schedule shall be filed by all Group II and Group III air carriers.

(b) Data applicable to acquisitions and data applicable to retirements shall be grouped and reported separately. The data reported within each group (acquisitions; retirements) shall be further subgrouped and reported as follows:

Items included in accounts 1607, 1608, 1707, and 1708, sold as a part of an airframe or aircraft sales transaction, shall also be identified by the name of the buyer. Other sales of items included in these accounts shall be reported in a separate group in aggregate for each property account affected.

(a) This Schedule shall be filed quarterly by all Group II and Group III air carriers and Group I air carriers that have annual operating revenues of $20 million or more.

(b) This schedule shall be filed for the overall or system operations of the air carrier.

(c) The statement of cash flows shall separately disclose the amount of net cash provided or used during the reporting period from the carrier's operating activities, investing activities and financing activities. The effect on cash and cash equivalents of the total amount of net cash provided or used during the quarter from each of the above activities shall be clearly disclosed so as to reconcile beginning and ending cash and cash equivalents.

(d) Carriers may use either the direct or indirect method of reporting cash flows. Under either method, the reporting of cash flows from investing and financing activities will remain the same. However, the reporting of cash flows from operating activities does differ between the two methods.

(e) For carriers electing to use the direct method, cash flows from operating activities are reported as gross amounts of the principal components of cash receipts and cash payments from operating activities, such as cash received from passengers and shippers, cash paid to suppliers, and cash paid to employees. Each carrier using the direct method shall provide as part of its statement of cash flows, a separate schedule that reconciles net income (as reported on Schedule P-1.2 in Account 9899) to cash flow from operating activities.

(c) Data pertaining to aircraft engines shall be reported on a group basis by type of engine and by type of aircraft to which related.

(d) Data in this schedule shall be grouped and subtotaled as data pertaining to airframes and data pertaining to aircraft engines. Data pertaining to nonoperating airframes and aircraft engines shall be reported in a group below the data for operating equipment. Data pertaining to airframes and aircraft engines obtained under operating and capital leases shall be reported, by type of lease, in a separately captioned grouping below nonoperating airframes and aircraft engines and subgrouped within those groups according to operating and nonoperating equipment.
