The ADOSC shall include the total outside service charges of both labour and material costs, but excluding transportation and taxes. 4.3 Hourly Airframe Direct Maintenance Cost ("ADMC") The following formula shall be used to calculate the hourly ADMC: ADMC = ADMMC + ADOSC T Where: ADMMC = Airframe Direct Maintenance Material Cost, ADOSC = Airframe Direct Outside Service Cost, T = Total flight hours for the Aircraft recorded for the applicable period. 4.4 Exclusion of In-House Labour Costs For more certainty, the parties agree that all labour costs incurred in-house by Buyer in maintaining
