U.S. Orders Inspections of Embraer Phenom 300 Jets Over Tail Flaw

BRAZIL · BUSINESS

A regulatory safety order in the United States has put a spotlight on one of Brazil’s most successful aircraft, requiring inspections of dozens of Embraer business jets after officials flagged a possible flaw in how a critical tail component was tested.

What the FAA ordered for the Phenom 300

The US Federal Aviation Administration, the agency that regulates civil aviation in the United States, published a new airworthiness directive for certain Embraer EMB-505 airplanes, the model marketed worldwide as the Phenom 300. An airworthiness directive is a legally binding order requiring owners and operators to fix a condition the regulator considers unsafe before an aircraft can keep flying. The order was entered in the Federal Register, the US government’s official gazette, and becomes effective on July 6.

The directive requires operators to inspect the left-hand and right-hand horizontal stabilizers of the affected jets and, where needed, to replace certain hinge-point and pitch-trim actuator attachment parts, along with the pitch-trim actuator itself. The horizontal stabilizer is the small wing-like surface at the tail that keeps the aircraft balanced in pitch.

Why the regulator stepped in

According to the FAA, the action was prompted by the possibility that some airplanes returned invalid results when the clearance, or backlash, of the horizontal stabilizer was tested, because incorrect procedures were followed during those checks. The agency warned that the flawed testing could have masked excessive play in the component.

Excessive clearance, the regulator said, could lead to an aeroelastic phenomenon that exposes the surrounding structure and systems to unacceptable vibration and reduces the controllability of the aircraft. The directive descends from a parallel order issued by Brazil’s National Civil Aviation Agency, the regulator for Embraer’s home country, which the FAA incorporated into its own requirements.

How many jets and at what cost

The FAA estimates the order affects 41 aircraft registered in the United States. It put the cost of the inspection at about $1,360 per airplane. If every repair allowed under the directive turns out to be necessary, the bill could reach roughly $14,950 per aircraft. The agency noted, however, that the manufacturer’s warranty could cover part or all of those costs, which would soften the financial hit for operators.

The FAA framed the measure as preventive, intended to head off a safety risk rather than a response to any reported accident. The directive states plainly that the unsafe condition, if left uncorrected, could result in unacceptable vibration levels and reduced control of the airplane.

What it means for Embraer

The Phenom 300 family is among the most-delivered light business jets in the world and a marquee product for Embraer, Brazil’s aerospace champion and one of the country’s most prominent industrial exporters. Inspection orders of this kind are a routine feature of aviation oversight and are usually coordinated between the FAA and Embraer’s home regulator, but they still draw attention to a flagship aircraft and to the manufacturer’s shares, which trade in both São Paulo and New York.

For now the scope is narrow: a defined list of US-registered jets, a modest per-aircraft cost, and a compliance deadline several weeks out. The episode underscores how closely Brazil’s signature aviation export is tracked by foreign regulators whose decisions shape where and how those jets can fly.
