The Outfit

A Palouse spray outfit,
run by the pilot who flies it.

Fender Air Service was incorporated in 1994 and has worked the same wheat country ever since. Darrell flies the airplanes. Linda keeps the books and answers the phone. No call center and no franchise, just a family that knows every draw and hilltop between Colfax and the Idaho line.

We fly out of the Port of Whitman Business Air Center southwest of Colfax, with a second strip up at Oakesdale, so we can be over your ground fast when the weather turns fit.

What We Do

Four ways we put it on by air.

From the first spring burndown to late-season fungicide, we cover the whole calendar. Liquid or dry, metered accurate, and kept on your ground instead of the neighbor's.

01

Aerial Spraying

Herbicide, fungicide and insecticide put on at speed, across the steep draws and soft ground a ground rig would rut up.

Burndown · Fungicide · Insecticide See spraying →
02

Aerial Seeding

Cover crops, cereal rye and pasture seed broadcast from the air, over standing stubble and steep hillsides.

Cover crops · Pasture · CRP See seeding →
03

Fertilizer, Liquid & Dry

Foliar feed and dry fertilizer laid down when the canopy is too tall or the field too soft to drive.

Foliar feed · Dry top-dress See fertilizer →
04

Precision, Low-Drift

Flown 6 to 10 feet off the deck and set down within a couple feet of target. Careful about the wind and your neighbors.

Why Growers Call Fender

Reasons to put your acres on our board.

Flying the Palouse since 1994

The owner is the one flying your fields.

Book Fender and you get Darrell in the cockpit and Linda on the phone. Same family, same country, every season since 1994. That is the whole pitch, and it is why the phone keeps ringing.

The owner flies every job

No rotating crew of strangers. The name on the airplane is the name in the seat.

We only fly the Palouse

One region, learned by heart. We know the power lines, the draws and the wind that comes up in the afternoon.

Two strips, quick turns

Colfax and Oakesdale mean short ferries and more flying in the hours the weather gives us.

Low and tight, low drift

Flown close to the crop and metered careful, so the product lands where you paid for it and stays put.

“I've been spraying a long time, and precision is everything. You put it on the crop and nowhere else.”

— Darrell Fender, Owner & Pilot
The Fleet

Turbine muscle and a classic biplane.

Purpose-built ag airplanes, kept sharp and flown hard through the season. Real airframes, real tail numbers.

What Growers Say

Trusted across the Palouse.

A few words from the growers we fly for, season after season.

★★★★★
“Darrell got my flag-leaf fungicide on in a tight window before the weather turned. Called in the morning, flown by afternoon, and the drift stayed off my neighbor's peas.”
Dale R.
Wheat & lentils · Steptoe
★★★★
“We have been flying with Fender for years because they know this ground and the wind on it. No wheel tracks through my stand, no fuss, and the bill matches what we agreed on.”
Kurt M.
Wheat & barley · Oakesdale
★★★★★
“When my garbanzos needed a burndown ahead of harvest, Linda had me on the schedule and Darrell was over the field the next morning. Clean job, low drift, done right.”

★★★★
“Aerial seeding on ground I could not get a drill across, and it came up even. These folks show up when they say they will and they treat you fair.”
