Frank Connor
Executive Vice President and 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 billion were up $175 million from a year ago, largely due to higher Citation jet volume of $93 million, aftermarket volume of $61 million and commercial turboprop volume of $59 million. Segment profit was $121 million in the first quarter, up $74 million from a year ago, largely due to the higher volume and mix of $55 million and favorable pricing net of inflation of $16 million. Backlog in the segment ended the quarter at $5.1 billion. Moving to Bell. Revenues were $834 million, down $12 million from last year due to lower commercial revenues of $32 million, largely reflecting the mix of aircrafts sold during the period, partially offset by higher military revenues.
Segment profit of $98 million was down $7 million, reflecting lower volume and mix, partially offset by favorable impact from performance. Backlog in the segment ended the quarter at $4.8 billion. At Textron Systems, revenues were $273 million, down $55 million from last year's first quarter due to lower volume of $59 million, primarily reflecting the impact of the U.S. Army's withdrawal from Afghanistan on our fee-for-service and aircraft support contracts. Segment profit of $33 million was down $18 million from a year ago due to lower volume and mix of $11 million described above and an unfavorable impact from performance of $9 million primarily reflecting lower net favorable program adjustments on our fee-for-service contracts.
Backlog in this segment ended the quarter at $2.1 billion. Industrial revenues were $838 million, up $13 million from last year, primarily due to a favorable impact of $46 million from pricing, principally in the Specialized Vehicles product line, partially offset by lower volume and the mix of $24 million, largely in the Fuel Systems and Functional Components product line due to the impact of global supply chain shortages on our auto OEM customers. Segment profit of $43 million was down $4 million from the first quarter of 2021, primarily due to lower volume and mix described above. Finance segment revenues were $16 million and profit was $9 million.
Moving below segment profit, corporate expenses were $44 million and interest expense was $28 million. Our manufacturing cash flow before pension contributions was $209 million in the quarter, up $138 million from last year's first quarter. In the quarter, we repurchased 2.2 million shares, returning $157 million in cash to shareholders. Beginning in the second quarter of 2022, Pipistrel will become part of Textron eAviation, a new business segment where we will combine our existing initiatives with Pipistrel's capabilities to accelerate our development of sustainable aviation solutions. This new reporting segment will include development expenses related to these efforts and Pipistrel's operating results.
For the remainder of the year, we expect revenues for the eAviation segment to be in the range of $30 million to $40 million and a segment loss of about $45 million, which reflects a net cost increase of about $20 million from the eAviation guidance we provided in January. On our January call, we provided guidance for the expected costs related to eAviation of about $30 million, which were included in our full year corporate expense guidance of about $150 million. We now expect corporate expense to be about $125 million reflecting the move of $25 million of expected eAviation cost to the new segment on a prospective basis.
For the full year, we're reiterating our EPS guidance of $3.80 to $4 per share, inclusive of the eAviation segment results. That concludes our prepared remarks. So Leah, we can open the line for questions.
