N7439M

N7439M is a Cessna 175, a single-engine piston aircraft operated by BROOKS RANDALL L, BROOKS LINDA E. SkyMeter has tracked 110 flights totalling 65 hours of airtime via ADS-B. The most frequent segment is 5AZ3 to 5AZ3. Service window in our records spans 385 days. Of those flights, 26 (23.6%) carry at least one detected incident: a go-around, unstable approach, stall warning, or runway excursion. The Cessna 175 has a 36 ft wingspan, a maximum takeoff weight of 2,450 lb.

About the Cessna 175

The Cessna 175 Skylark represents one of general aviation's more interesting commercial missteps: a promising idea undermined by mechanical complexity. Introduced in 1958 as a higher-performance sibling to the wildly successful 172, the 175 paired the familiar Skyhawk airframe with a geared Continental GO-300 engine producing 175 horsepower. The geared propeller allowed the engine to spin at higher RPM while the prop turned more slowly, theoretically delivering better performance and fuel efficiency. On paper, the 175 offered a 15-knot cruise advantage over the 172 and superior climb rate, making it attractive to pilots seeking more capability without stepping up to a retractable-gear aircraft.

In practice, the geared engine proved troublesome. The reduction gearbox required careful maintenance and was prone to expensive failures if operators didn't follow Continental's strict procedures, particularly the mandatory five-second pause at 1,200 RPM during runup to allow oil pressure to build in the gears. Many rental operators and private owners accustomed to simpler direct-drive engines found this finicky, and gear failures became common enough to tarnish the type's reputation. Parts availability declined as Continental discontinued the GO-300, and insurance costs climbed. By 1962, after just 2,106 examples, Cessna quietly discontinued the 175 and refocused on the 172, which would go on to become the most-produced aircraft in history.

Today the 175 occupies an unusual niche among collectors and budget-conscious pilots. Many have been converted to standard Lycoming engines, effectively turning them into 172s with different data plates. Unconverted examples with well-maintained GO-300s can still deliver that original performance promise, cruising around 140 knots at altitude, genuinely faster than a contemporary 172. The type's brief production run and mechanical quirks make it a footnote in Cessna's history, but one that illustrates how even minor engineering decisions can determine an aircraft's commercial fate. SkyMeter has tracked flights across airframes and operators, with the most frequently observed.
