Frank Connor
Executive Vice President & Chief Financial Officer at Textron
Thanks, Scott. And good morning, everyone. Let's review how each of the segments contributed, starting with Textron Aviation. Revenues at Textron Aviation of $1.2 billion were up $386 million from a year ago, largely due to higher Citation jet volume of $290 million, aftermarket volume of $62 million and commercial turboprop volume of $48 million. Segment profit was $98 million [Phonetic] in the third quarter, up $127 million from a year ago, largely due to the higher volume and mix of $96 million and favorable pricing net of inflation of $22 million. Backlog in the segment ended the quarter at $3.5 billion.
Moving to Bell. Revenues were $769 million, down $24 million from last year, largely reflecting lower military revenues. Segment profit of $105 million was down $14 million, primarily due to lower military revenues. Backlog in the segment ended the quarter at $4.1 billion.
At Textron Systems, revenues were $299 million, down $3 million from last year's third quarter due to lower volume of $39 million at Air Systems, which primarily reflected the impact from the U.S. Army's withdrawal from Afghanistan on its fee-for-service contracts, partially offset by higher volume, primarily at ATAC and Electronic Systems. Segment profit of $45 million was up $5 million to a favorable impact from performance and other. Backlog in the segment ended the quarter at $2.2 billion.
Industrial revenues were $730 million, down $102 million from last year, reflecting lower volume and mix of $156 million, primarily at Fuel Systems and Functional Components, reflecting order disruptions related to the global auto OEM supply shortages, partially offset by favorable impact of $44 million from pricing, largely at Specialized Vehicles.
Segment profit of $23 million was down $35 million from the third quarter of 2020, primarily due to the lower volume and mix described above, partially offset by higher pricing net of inflation at Specialized Vehicles. Finance segment revenues of $11 million - were $11 million and profit was $8 million.
Moving below segment profit. Corporate expenses were $23 million and interest expense was $28 million. With respect to our 2020 restructuring plan, we recorded pretax charges of $10 million on the special charges line. Our manufacturing cash flow before pension contributions was $271 million in the quarter and $851 million year-to-date as compared to $129 million for the corresponding 9 month period in 2020. Year-to-date, our cash generation reflects improved working capital management, which includes more linearity in quarterly aircraft deliveries and higher customer deposits at aviation from an increased backlog.
In the quarter we repurchased approximately 4.2 million shares, returning $299 million in cash to shareholders. We're raising our expected full year guidance for adjusted EPS to a range of $3.20 to $3.30 per share. This includes revised tax guidance at effective rate of 15.5% for the full year. We're also raising our outlook for manufacturing cash flow before pension contributions to a range of $1 billion to $1.1 billion, up $200 million from our prior outlook, with planned pension contributions of $50 million.
That concludes our prepared remarks, so we can open the line for questions.
